perf(frontend): share one cached fetch for /api/auth/settings and /api/tools (#5997)

* perf(frontend): share one cached fetch for settings and tools

/api/auth/settings was fetched independently by eight modules and /api/tools by
three on a single load — 4 and 3 requests measured — and any two of those
callers could observe a different snapshot of the same object. chatRenderer.js
is imported under three different ?v= query strings, so it is three separate
module instances each issuing its own /api/tools request.

appConfig.js holds one promise per endpoint, so concurrent and later callers
share it. Every writer invalidates: the settings panel routes its 16 saves
through a single helper, and the admin tools save drops both snapshots because
that route persists disabled_tools into the same settings store. A rejected
fetch clears its slot rather than being memoised, so one blip at boot cannot
leave keybinds, TTS and the search provider on defaults for the session.

The settings panel keeps reading directly: it is the writer and edits what it
reads, so it must see authoritative state.

Cold load, Resource Timing: /api/auth/settings 4 -> 1, /api/tools 3 -> 1, and
0 settings requests on the first load after a login, because the cache now
consumes the sessionStorage prefetch that login.html writes.

Fixes #5996

* fix(admin): refetch tool state when the Agent Tools panel opens

The shared cache made Admin > Tools render the boot snapshot on every
reopen. Its save posts the whole disabled list rebuilt from the checkboxes,
so a tool disabled out of band (the manage_settings tool, another tab) came
back enabled on the next unrelated toggle. Reproduced against the running
app: with api_call disabled by a separate client, toggling app_api off
posted ['app_api'] and silently re-enabled api_call.

The panel now drops the shared entry before reading it, which restores what
dev does today and keeps the startup read that chatRenderer.js shares. Cold
load is still 1 request each for /api/auth/settings and /api/tools, and the
panel costs the same 2 requests per open as dev.

* fix(static): preserve concurrent tool setting changes

+//
+// 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.

+"""Pin the shared config cache in static/js/appConfig.js.
+
+Background: /api/auth/settings was fetched independently by six modules and
+/api/tools by three (chatRenderer.js is imported under three different ?v=
+query strings, so it is three separate module instances) — 4 and 3 requests on
+one cold load. Beyond the redundant work, each caller could observe a different
+snapshot of the same object. appConfig.js gives them one promise each.
+
+The two properties that matter are opposites, so both are tested here:
+concurrent and later callers must NOT refetch, and a caller after a write MUST
+see the new value — which only holds if every writer invalidates. The last test
+is a source scan that checks exactly that, since a forgotten invalidation
+serves a stale settings object for the rest of the session, which is worse than
+the duplicate fetches this replaces.
+
+Driven through `node --input-type=module` so the real module runs, same idiom as
+test_esc_menu_stack_js.py. The module source is inlined rather than imported by
+path because the repo has no `"type": "module"` in package.json; appConfig.js
+has no imports of its own, so inlining is exact. `fetch` and `sessionStorage`

+The registry is what keeps a lazily-loaded panel honest: it must import a
+panel's module exactly once no matter how many times the user clicks, it must
+fail loudly on a name nobody registered (rather than handing back `undefined`
+and blowing up somewhere unrelated), and it must not memoise a *failed* load —
+otherwise a panel that failed to load once while offline would stay broken for
+the rest of the session.
+
+`createPanelLoader` is exercised with stub thunks so these tests need no DOM and
