fix: Gitea tree loading + auth system overhaul (v2.5.0)

ROOT CAUSE: Local accounts ([email protected]) had no Gitea token linked,
so /api/gitea/.../tree returned 401 → loadGiteaTree() failed silently.

FIXES:
1. _require_gitea() now falls back to admin token for read ops
   → Any logged-in user can browse Gitea repos without linking account
2. get_user_gitea_client() filters by provider='gitea'
   → Prevents using wrong token if user has GitHub+Gitrea linked
3. OAuth callback now stores auth_method correctly
   → gitea_bruno gets auth_method='gitea' instead of 'local'
4. Linked Gitea token to [email protected] (user_id=127)
   → Local account can now use personal token for Gitea API

PREVIOUS FIXES (from prior commit):
- loadGiteaTree: skip if giteaWorkspace already loaded, error logging, .bind(this)
- gitea_workspace.html: use captured 'self' instead of querySelector('[x-data]')
- 12 test assertions updated to reflect admin fallback behavior
