Fix shutdown waitgroup panic (#35676)
This PR fixes a panic issue in the WaitGroup that occurs when Gitea is
shut down using Ctrl+C.
It ensures that all active connection pointers in the server are
properly tracked and forcibly closed when the hammer shutdown is
invoked.
The process remains graceful — the normal shutdown sequence runs before
the hammer is triggered, and existing connections are given a timeout
period to complete gracefully.

This PR also fixes `no logger writer` problem. Now the log close will
only be invoked when the command exit.

- Fixes #35468
- Fixes #35551
- Fixes #35559
- Replace #35578
