feat(server): add native Gitea authentication and transport

[kalvenschraut]

T3 needs a native authenticated transport for self-hosted Gitea. Add server-side web-root/token configuration, account probing, typed errors, bounded responses, rate-limit timing, and same-origin API paths. Fetch redirects are disabled so writes and credentials cannot be replayed outside the configured API root; successful no-content responses are accepted.

Validation: 14 focused transport tests, including the production Fetch redirect setting and HTTP 204 deletion responses; server typecheck. Verified authenticated read requests against the designated Gitea 1.27.3 server. This is the foundation of the native Gitea stack; provider discovery is wired by the next PR.

Final stack validation at 256fd6fe5: 228 focused tests passed, followed by 61 API/workflow cases and the final team-recovery regression; server typecheck and targeted lint passed. The live settle-on-merge E2E previously passed with fixture cleanup. Companion Gitea backend and focused integration tests passed, including native revert across all five merge styles.

Implementation: Codex (GPT-6). Sensitive review: GPT-6 Astra. Design review: Claude Fable 5.1 via Claude Code CLI.

Summary by CodeRabbit

• New Features

  • Added a startup warning when Gitea is configured with a non-loopback HTTP URL, noting that access tokens are transmitted without encryption.

• Bug Fixes

  • Improved cleanup and timeout handling for Gitea API requests.

• Tests

  • Added comprehensive coverage for authentication, URL validation, redirects, rate limits, response-size limits, schema validation, error handling, and deletion responses.

📝 Walkthrough

Walkthrough

Changes

The PR adds Gitea API tests for configuration, authentication, URL restrictions, redirects, status mapping, response limits, schema validation, and deletion responses. It also adds an HTTP warning and scopes client and timeout resource handling.

Gitea API Safety and Lifecycle Updates

Layer / File(s)	Summary
Configuration and URL validation apps/server/src/sourceControl/GiteaApi.test.ts	Adds tests for mocked service construction, authentication configuration, URL restrictions, base-URL normalization, and invalid configuration diagnostics.
Request safety and response handling apps/server/src/sourceControl/GiteaApi.ts, apps/server/src/sourceControl/GiteaApi.test.ts	Warns for non-loopback HTTP URLs, scopes HTTP client execution, controls redirects, maps responses, bounds response sizes, validates schemas, and handles empty deletion responses.
Timed request resource cleanup apps/server/src/sourceControl/GiteaApi.ts	Scopes timed request execution before timeout handling and error conversion.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 30fb4

Gitea server authentication and transport handling now include safer URL and redirect behavior, bounded response processing, typed error handling, and cleanup for timed requests. No concrete current-head merge-blocking risk remains.

- Line 67: Update the Gitea base-URL validation around the protocol allowlist to
prevent cleartext token transmission: reject http: URLs for non-loopback hosts,
while permitting loopback HTTP URLs, or emit an equivalent startup warning
documenting the exposure when such a URL is configured with a token.
- Around line 175-197: In the non-2xx response branch of the Gitea API request
flow, cancel response.stream before yielding the GiteaApiError. Ensure
cancellation occurs for every error response, including failures while
processing the error, while preserving the existing error classification and
details.
