feat: Improve OurDBFS file system persistence and ID generation

- Fixed ID generation for files and directories in OurDBFS,
  preventing collisions and improving data integrity.  This
  ensures that IDs are consistently and uniquely assigned.
- Updated save methods to correctly update the `metadata.id`
  field across all FSEntry types (File, Directory, Symlink).
  This change solves a previous issue where IDs weren't being
  properly persisted.
- Added incremental mode to OurDB, improving performance for
  large datasets.  This allows for more efficient updates
  instead of full overwrites.
