ci: Test TMT patch from cgwalters/tmt fork

Update debug-tmt.yml to install TMT from cgwalters/tmt's
fix-queue-debug-logging branch instead of PyPI. This tests
the patch that fixes DebugLevelFilter to reject DEBUG messages
without TMT's custom details attribute.

Changes:
- Install tmt from git+https://github.com/cgwalters/tmt.git@fix-queue-debug-logging
- Add verification step to confirm the patch is applied
- Update debug-tmt.sh to count and report DEBUG lines
- Add success/failure reporting for the fix

Expected result: 0 DEBUG:tmt.* lines in output (vs 100k+ without patch)
