Case sync: refresh remote URL with current token before each push

Cases failed to push silently after the Gitea token in Infisical was
rotated: the embedded credential in each case repo's origin URL was
the old token, the rotation never propagated, and capture_output=True
hid the auth failure as a logger.warning. Three cases (1033-25,
1130-25, 1194-25) accumulated unpushed commits over weeks before
this was noticed.

Fixes the root cause in two places: web/gitea_client.py for uploads
through the FastAPI endpoint, and mcp-server/services/git_sync.py
for case_update / document_upload through MCP tools (which previously
committed but never pushed at all).

The new commit_and_push helper:
- re-injects the current GITEA_ACCESS_TOKEN into the existing origin
  URL on every call, so pushes survive token rotation
- logs push failures at WARNING with the actual stderr (the previous
  code suppressed errors entirely)
- continues to push even when the commit was a no-op, in case earlier
  commits are still unpushed
