Console: Seats spinner replaces Add/Remove pilot in relay mode

Rows are capacity + per-seat defaults now -- joiners auto-populate them
live and launch trims to whoever is seated, so hand-managing rows is
busywork.  A Seats spinner (1-8) maintains the row count in relay mode;
Add pilot / Remove selected remain for mesh mode, where explicit
addresses matter.
