get_recent_images and search_images_by_prompt take limit/offset so the recent
and search image routes no longer over-fetch a 5000-row window and slice it.
generate_content_hash, PromptModel.migrate_database and find_duplicates had no
callers outside their own tests. The isolated logger tests re-apply their
thread filter after update_config rebuilds the handlers. Long lines in the
touched database and image modules are wrapped so the full flake8 hook passes.
truncate_logs emptied prompt_manager.log through a second open(), leaving the
rotating handler's stream at its old offset: the next record was written past
the new end (zero padding on POSIX) and tell() still reported the old size, so
the file rolled over and resurrected the backup that had just been deleted.
It also logged once per file from inside the deletion loop, which could do the
same with a small size limit. The main log is now truncated through the
handler's own stream and a single summary line is logged afterwards.
The diagnostics message no longer carries the absolute path, the restore test
closes its raw sqlite connections before the live file is replaced, the logs
tests declare their own folder_paths base directory, and the isolated logger
filters every handler to the test thread.
