feat: rename the database from Settings, keeping all config

Adds a Rename button to Settings -> Database: renames the current SQLite database
(e.g. opslog.db -> F4BPO.db) while preserving every setting/profile, unlike New
database which starts empty. Implemented as a VACUUM INTO copy + pointer switch;
the old file (open and locked now) is scheduled via config.json delete_pending
and removed, with its -wal/-shm sidecars, on the next launch.
