Restore local Whisper test coverage on Python 3.13

[ftnext]

Summary

Restore the local Whisper test coverage on Python 3.13.

This change:

• runs the whisper-local and faster-whisper dependency set again on Ubuntu for Python 3.13
• updates the local Whisper test skips so they are skipped only on Python 3.14 and later
• keeps the lighter dependency set for Python 3.14 unchanged

Verification

• python3 -m py_compile tests/recognizers/whisper_local/test_whisper.py tests/recognizers/whisper_local/test_faster_whisper.py
• git diff --check
• pytest -q tests/recognizers/whisper_local/test_whisper.py tests/recognizers/whisper_local/test_faster_whisper.py in the local Python 3.14 environment stopped at collection because numpy was not installed
