Fix: Prevent Flask hot reload from hanging due to early thread startup (#7966 )

**Fix: Prevent Flask hot reload from hanging due to early thread
startup**

### What problem does this PR solve?

When running the Flask server with `use_reloader=True` (enabled during
debug mode), modifying a Python source file would trigger a reload
detection (`Detected change in ...`), but the application would hang
instead of restarting cleanly.

This was caused by the `update_progress` background thread being started
**too early**, often within the main module scope.
This issue was reported in
[#7498](https://github.com/infiniflow/ragflow/issues/7498).

### Type of change

- [x] Bug Fix (non-breaking change which fixes an issue)
---

**Summary of changes:**
- Wrapped `update_progress` launch in a `threading.Timer` with delay to
avoid premature thread execution.
- Marked thread as `daemon=True` to avoid blocking process exit.
- Added `WERKZEUG_RUN_MAIN` environment check to ensure background
threads only run in the reloader child process (the actual Flask app).
- Retained original behavior in production mode (`debug=False`).
