fix: podcast failure recovery and retry (1.7.3) (#595)

* fix: surface podcast errors and enable retry for failed episodes

Fixes #335, #300

Re-raise exceptions in podcast command so surreal-commands marks jobs as
failed instead of completed. Surface error_message in API responses and
add a retry endpoint that deletes the failed episode and re-submits the
generation job. Frontend shows error details on failed episodes with a
retry button. Translations added for all 8 locales.

* fix: bump podcast-creator to >= 0.10

Fixes #302

* chore: release 1.7.3 - podcast failure recovery and retry

Bump podcast-creator to >= 0.11.2, disable automatic retries for
podcast generation to prevent duplicate episodes, and bump version
to 1.7.3.

Fixes #211, #218, #185, #355, #300, #302

* fix: resolve TypeScript error in handleRetry return type
