MIDI hold and auto-fix move a link joined by name to the owning Mac's wired address

- WS 2026-10-21: FOH Mac mini joined ProPresenter's session by name; hold said "no automatic fix". Now the
  address comes from the link's own check, else the Mac that owns that session (wired SSH / ingest address +
  session port); auto-fix does it too, never while a HyperDeck records
- WS: FOH Mac mini <-> ProPresenter watched (FOH PROP); auto-fix moved it to 10.2.1.12:5004 by itself
