Fix diagnostics/session usage limit handling and voice-call numeric CLI validation.
- Treat explicit zero, negative, and non-finite diagnostics/session limits as empty results instead of falling back to defaults.
- Reject invalid, non-finite, and fractional voice-call numeric flags.
- Add focused tests and a live repro proof for the canonical edge cases.
Fixes#82646, #82650, #82651, #82653.

TTS output as trusted local media and pass the flag through the TTS-only
final payload WebChat consumes after block streaming.
