Vito Sansevero 2b3cd5cbfb fix: harden database restore and keep server paths out of admin responses
Restore: verify_database_file and restore_from_file run through
_run_in_executor; the upload is also opened read-only with
PRAGMA trusted_schema=OFF and refused when sqlite_master lists a trigger
or a view (a prompts database has neither, a crafted one could use them
to run SQL against the live data); at most MAX_SAFETY_BACKUPS (10)
'<db>.backup_*' files are kept next to the live database, oldest first.

Responses: backup_created and the maintenance statistics database_path
go through _public_path, and backup/restore failure messages through
_public_error, so no absolute server path appears in an admin body.

"""Route tests for GET /prompt_manager/backup and POST /prompt_manager/restore.
The backup must include rows still sitting in the WAL, the restore must
stream the upload to disk, reject anything that is not a healthy prompts
database and leave the live database untouched when it does.
