docs(config): sweep retired .internal names — Gitea at git.schweitz.net, connectors by IP

Jeroen confirmed the .internal-to-.net proxy migration was intentional
(2026-07 weekend maintenance): git.schweitz.internal's vhost is gone,
git.schweitz.net is live with a LE cert and AdGuard LAN hairpin.
tea-cli.md + local-services.md repointed (tea's own config already
switched). tooling/db/config.json: the bare tower-of-joy hostname has
no DNS entry since the migration — Stable Audio/Trellis endpoints now
by IP. Workshop archives under docs/workshops/ keep their historical
.internal mentions (records, not operative config).
