When the most recent scheduled import completed with errors, surface the
failure in the persistent app shell:
- A warning MessageBar appears at top of main content area
- An amber badge is rendered on the Blocklists sidebar nav item
Backend: add last_run_errors: bool | None to ScheduleInfo model and
populate it in get_schedule_info() from the latest import_log row.
Frontend: extend ScheduleInfo type, add useBlocklistStatus polling hook,
wire both indicators into MainLayout.
Tests: 3 new service tests + 1 new router test (433 total, all pass).
_is_not_found_error in jail_service did not match the concatenated form
'unknownjailexception' that fail2ban produces when it serialises
UnknownJailException, so JailOperationError was raised instead of
JailNotFoundError and every ban attempt in the import loop failed
individually, skipping all 27 840 IPs before returning an error.
Two changes:
- Add 'unknownjail' to the phrase list in _is_not_found_error so that
UnknownJailException is correctly mapped to JailNotFoundError.
- In blocklist_service.import_source, catch JailNotFoundError explicitly
and break out of the loop immediately with a warning log instead of
retrying on every IP.
