fix(personal): bound multi-file upload memory

/api/personal/upload and DELETE /api/personal/file mutated the same
vector and tracking state add/remove/reload serialize on, outside
_index_job_lock and inline on the event loop.

Both now stage async work on the loop, then run the complete transition
(vector writes, disk change, personal_docs_manager update) in one
offloaded critical section under the shared lock, acquired before the
offload so queued requests park on the loop rather than pinning a
threadpool worker.

Adds add-vs-upload and add-vs-file ordering regressions.

+- **Reserved usernames:** `internal-tool`, `api`, `demo`, `system` cannot be registered or renamed into. Defined in `core/auth.py:RESERVED_USERNAMES`.
   - `internal-tool` is security-critical: `core/middleware.py:require_admin` treats any request where `request.state.current_user == "internal-tool"` as the in-process tool loopback and grants admin unconditionally. A real account with that name would silently pass every `require_admin` check.
 - **Orphan sessions:** `validate_token` re-checks that the user record still exists on every call. A deleted user's cookie is dropped on next request rather than continuing to authenticate.

 `ALLOWED_ORIGINS` lists exact permitted origins for cross-origin browser/API clients; ordinary same-origin reverse-proxy access usually does not need a special CORS entry.
 
-#### Faster over the network: HTTP/2
-
-The frontend is raw ES modules with no bundler, so a page load is a few hundred
-small same-origin requests. Over HTTP/1.1 browsers typically allow only a small
-number of concurrent connections per host (commonly around six), so many of
-those requests are serialized across multiple round trips. On localhost that
-costs almost nothing. Over a LAN, VPN, or remote link it can become a major
-part of load time, especially as latency increases.
-
-HTTP/2 multiplexes them onto one connection and the serialisation disappears.
-Odysseus needs no changes for this — uvicorn keeps speaking HTTP/1.1 on
-loopback and the proxy speaks HTTP/2 to the browser. Mainstream browsers
-negotiate HTTP/2 for normal web pages over TLS; they do not use the cleartext
-h2c mode here, so browser-facing HTTP/2 requires a certificate. The
-`--ssl-certfile` route in *HTTPS + LAN/Tailscale exposure* above gives you
-HTTPS but not HTTP/2 — uvicorn does not speak it.
-
-**1. Install Caddy.** See the [install docs](https://caddyserver.com/docs/install)
-for your platform; on macOS, `brew install caddy`.
-
-**2. Write a `Caddyfile`.** Pick the block that matches how you reach the
-machine. Replace `7000` if Odysseus listens elsewhere — the macOS start script
-uses `7860`.
-
-Public domain, Caddy obtains and renews the certificate itself:
-
-```
-odysseus.example.com {
-	reverse_proxy 127.0.0.1:7000
-}
-```
-
-Tailscale, no public DNS needed — `tailscale cert` issues a browser-trusted
-certificate for a tailnet name and writes `<domain>.crt` and `<domain>.key`:
-
-```bash
-tailscale cert myhost.tailnet-name.ts.net
-```
-
-```
-myhost.tailnet-name.ts.net {
-	tls /path/to/myhost.tailnet-name.ts.net.crt /path/to/myhost.tailnet-name.ts.net.key
-	reverse_proxy 127.0.0.1:7000
-}
-```
-
-LAN with your own certificate — same shape, your own files:
-
-```
-odysseus.lan {
-	tls /path/to/cert.pem /path/to/key.pem
-	reverse_proxy 127.0.0.1:7000
-}
-```
-
-Give `tls` absolute paths: a service starts in a working directory you did not
-choose. If port 443 is already taken, append a port to the site address
-(`odysseus.example.com:8443`) and use it in the URL. That alone does not free
-port 80 — Caddy still binds it for the HTTP-to-HTTPS redirect, and fails to
-start with `listen tcp :80: bind: address already in use` if something else
-holds it. Turn the redirect off with a global block at the top of the file:
-
-```
-{
-	auto_https disable_redirects
-}
-```
-
-**3. Run it in the foreground first:**
-
-```bash
-caddy run --config ./Caddyfile
-```
-
-Once that works, run it as a service:
-
-```bash
-brew services start caddy          # macOS — reads $(brew --prefix)/etc/Caddyfile, not ./Caddyfile
-sudo systemctl enable --now caddy  # Linux, if your package installed the unit
-```
-
-Odysseus's own service is unchanged; the proxy runs alongside it. Under Docker,
-run the proxy as another container, or on the host pointing at the published
-port.
-
-**4. Point Odysseus at the new origin** in `.env`, then restart it.
-
-A proxy that exposes the HTTPS request scheme to Odysseus needs no `SECURE_COOKIES` setting. Only force it on when the proxy cannot expose that scheme:
-
-```bash
-# only if the proxy cannot expose the external HTTPS scheme to Odysseus:
-SECURE_COOKIES=true
-# only if you use remote MCP servers with OAuth:
-OAUTH_REDIRECT_BASE_URL=https://odysseus.example.com
-```
-
-Gmail OAuth needs nothing here when the proxy runs on the same host: the
-redirect URI is built from the incoming request, and uvicorn rewrites the
-scheme from `X-Forwarded-Proto` for proxies it trusts — by default only
-`127.0.0.1`. A proxy in a separate container or on another machine is not
-trusted, so pin the URI there:
-
-```bash
-GOOGLE_OAUTH_REDIRECT_URI=https://odysseus.example.com/api/email/oauth/google/callback
-```
-
-(uvicorn's own `FORWARDED_ALLOW_IPS` widens that trust, but it has to be in the
-environment uvicorn starts with — `.env` is read by the app afterwards, too
-late for it to take effect.)
-
-**5. Confirm HTTP/2 is really on:**
-
-```bash
-curl -s -o /dev/null -w '%{http_version}\n' https://odysseus.example.com/
-# 2
-```
-
-The status code is not the thing to check here — a logged-out request redirects
-to the login page, so `curl -I` shows `HTTP/2 302`, and the `HTTP/2` prefix is
-the part that matters. The browser reports the same in the Network panel's
-Protocol column (`h2`); in Chrome and Firefox that column is hidden until you
-enable it by right-clicking the column headers.
-
-Three things bite when moving an existing install behind TLS:
-
-- Leave `SECURE_COOKIES` unset when Odysseus can see the external HTTPS scheme;
-  the cookie then follows the request automatically. If your proxy cannot expose
-  that scheme, set `SECURE_COOKIES=true` **at the same time** you stop serving
-  plain HTTP, not before. An explicit `true` applies to every login, so while an
-  HTTP entrypoint is still reachable the browser will reject the `Secure` cookie
-  there and login will appear to loop.
-- `OAUTH_REDIRECT_BASE_URL` defaults to `http://localhost:7000`. Unlike the
-  Gmail redirect URI it cannot be derived from a request — it is registered
-  with each MCP authorization server up front — so set it to the external
-  origin if you use remote MCP servers over OAuth.
-- Odysseus sends `Strict-Transport-Security` once it sees `X-Forwarded-Proto:
-  https`. HSTS applies to the whole hostname and ignores the port, so any other
-  plain-HTTP service on that same hostname becomes unreachable in browsers that
-  have visited Odysseus. Give Odysseus its own hostname, or strip the header at
-  the proxy (`header_down -Strict-Transport-Security` in Caddy).
-
-Server-sent events are not buffered by this configuration, so chat streaming
-arrives token by token; add `flush_interval -1` inside the `reverse_proxy`
-block if you want that pinned explicitly. nginx needs `proxy_buffering off;`
-for the same reason.
-
-Changing the external origin also affects state scoped to it. Service workers
-and their caches are origin-scoped, so moving to a different origin starts with
-a cold load. Cookies follow their own domain/path/security rules rather than
-being port-scoped: changing the hostname normally requires a new login, while
-changing only the scheme or port does not by itself guarantee that existing
-cookies disappear.

-// One shared, invalidatable cache for the two config endpoints that every
-// module wants at startup.
-//
-// Before this, /api/auth/settings was fetched independently by six modules and
-// /api/tools by three, none of them aware of the others — 4 and 3 requests on a
-// single cold load. Worse than the requests: each caller could observe a
-// different snapshot of the same object, and chatRenderer.js is imported under
-// three different ?v= query strings, so it is three separate module instances
-// each issuing its own /api/tools fetch. Caching here fixes both, because the
-// cache lives in one module every instance imports by the same specifier.
-//
-// URLs are bare paths on purpose. The callers that used `${API_BASE}/api/...`
-// resolved to the identical URL — API_BASE is `window.location.origin`
-// (app.js) — so nothing about the request changes for them.
-//
-// WRITERS MUST INVALIDATE. Anything that POSTs /api/auth/settings calls
-// invalidateSettings(); anything that POSTs /api/tools calls invalidateTools()
-// *and* invalidateSettings(), because that route persists `disabled_tools`
-// into the same settings store (routes/model_routes.py). Miss one and the UI
-// serves a stale settings object for the rest of the session, which is worse
-// than the duplicate fetches this replaces.
-//
-// The resolved object is shared by reference, so treat it as read-only: copy
-// before mutating (`{ ...await getSettings() }`).
-
-// Written by login.html immediately before it redirects to '/', so the first
-// load after a login can skip the request entirely. Consumed once per page
