docs(media): what a verification verdict actually means, and what a rollback can undo

Three things the 2026-10-31 five-library relayout taught, written where the
next operator reads them:

- A verify run must open the servers' databases plain `mode=ro`. Both keep
  their libraries in WAL mode; `immutable=1` skips the write-ahead log, so a
  scanner's own committed rows read as missing and the read can fail as
  "database disk image is malformed". The census page claimed immutable — now
  it says what the code does.
- "No row at the destination" splits into four classes, and only REAL (no row
  at dst AND the file still at src) is the relayout's own damage. Phantom rows
  naming a pre-move path are normal behaviour for both servers. And the owning
  server decides whether a pass can convict: Jellyfin holds no audiobook
  library, so that journal verifies against Plex or it proves nothing.
- A chain of passes rolls back newest journal first, or the tool refuses; the
  refusals measured that day are the tool working, not failing.

The music and audiobook arms moved to their own pages (progressive disclosure;
the parent drops 175 lines and stays the owner of the shared gates, the
executor, the journal law and the rollback). Stale per-run counts destroyed:
episode counts, byte sizes, move tallies for a pass that already happened.
