fix(gitea): address review feedback on diff size limiting
- Add concurrency safety note to MaxDiffSize field documentation, mirroring the existing note on RetryBackoff - Consolidate six individual test functions into a single table-driven test (TestGetPullRequestDiff_SizeLimits) reducing repetition - Add //nolint:errcheck annotation to test handler w.Write calls
