Fix report draft save and microphone startup

- Allow draft reports to be saved without patient name or hospital ID while keeping completed reports strictly validated.

- Preserve completed-report identity validation when updating existing reports by checking merged old and new values.

- Show real API save errors in the report editor and send expired sessions back to login instead of reporting a generic backend outage.

- Guard speech startup for missing getUserMedia or AudioContext support and explain localhost/HTTPS microphone requirements.

- Add report schema tests covering draft identity fields and completed-report validation.

- Update AGENTS and docs for report editor behavior, feature status, progress, and testing coverage.
