feat(gitea): add Gitea/Forgejo as a git provider
Full parity with the existing GitLab provider:
- Server module packages/web/server/lib/gitea (auth/client/repo/routes + docs + tests)
with Gitea REST v1 API, PAT + base URL auth, multi-account storage
- Shared GiteaAPI types and web API client
- Provider detection generalized with user-configurable custom domains
per provider (github/gitlab/gitea), additive with built-in defaults
(github.com, gitlab.com) and connected-account hosts; precedence
github -> gitlab -> gitea
- Gitea PR view, issues section, pickers, integration dialog, branch
PR status helper, settings UI (PAT + base URL + custom domains)
- Magic prompts (gitea.pr.review, gitea.issue.review) and full 11-locale
i18n parity
