refactor(rebrand): update GitHub App slug to loopover-orb (#4772) (#5612)

Closes #4772. The GitHub App itself was renamed "Gittensory Orb" ->
"Loopover ORB" directly in GitHub settings (confirmed resulting slug:
loopover-orb, via https://github.com/apps/loopover-orb) -- in-place
rename, not a new App registration, so existing installations and
webhook deliveries are unaffected (keyed by the App's immutable ID,
not its slug).

Also updated on GitHub's side as part of the same change: Homepage
URL -> https://loopover.ai; a second OAuth callback URL added for
https://api.loopover.ai/v1/orb/oauth/callback (the old
gittensory-api.aethereal.dev one stays registered until the
PUBLIC_API_ORIGIN flip lands separately); Webhook URL ->
https://api.loopover.ai/v1/orb/webhook (safe immediately -- that
domain already routes to the same live Worker as the old one, from
the earlier domain-wiring work).

Code-side, the only real reference to the App's actual slug is
PUBLIC_GITHUB_APP_SLUG in src/services/subnet-interface.ts -- a
hardcoded product-identity constant (not env-driven) used to build
the install-URL descriptor served to the Bittensor subnet registry.
Updated it + the two tests asserting its value.

Everything else matching "gittensory-orb"/"gittensory-orb[bot]"
across the test suite (self-authored-detection fixtures, webhook
sender-login test data) belongs to a DIFFERENT, already-fully-deleted
review App (its own GITHUB_APP_SLUG env var was removed from
wrangler.jsonc back on 2026-07-12) -- those are arbitrary,
internally-consistent test strings unrelated to the Orb App's real
identity, not production values, so left untouched.

apps/gittensory-ui/src/routes/docs.self-hosting-release-checklist.tsx's
"gittensory-orb@0.1.0" Sentry-release-id mention is a historical
record of an actual past release and is deliberately never edited,
same as CHANGELOG.md.

## Test plan

- [x] Full local gate (`npm run test:ci` + `npm audit --audit-level=moderate`) green.
- [x] Confirmed via a live fetch to https://github.com/apps/loopover-orb that the App rename produced
      exactly the expected slug before touching any code.
