* [enhancement]: Provide native backup/restore mechanism
- db.go: add Backup/Restore functions that utilize Sqlite's built-in online backup mechanism
- support automatic backup with schedule, limit number of files
- provide commands to manually backup/restore Navidrome
Notes:
`Step(-1)` results in a read-only lock being held for the entire duration of the backup.
This will block out any other write operation (and may hold additional locks.
An alternate implementation that doesn't block but instead retries is available at https://www.sqlite.org/backup.html#:~:text=of%20a%20Running-,database,-%2F*%0A**%20Perform%20an%20online (easily adaptable to go), but has the potential problem of continually getting restarted by background writes.
Additionally, the restore should still only be called when Navidrome is offline, as the restore process does not run migrations that are missing.
* remove empty line
* add more granular backup schedule
* do not remove files when bypass is set
* move prune
* refactor: small nitpicks
* change commands and flags
* tests, return path from backup
