feat(rotator): multiple rotors of any type, plus a CAT PTT hotkey

Settings -> Rotator is now a list like the amplifiers: add/remove rotors,
mix PstRotator / Rotator Genius / ARCO, and a Rotator Genius can drive both
its ports (one entry = two rotors). The compass gains a rotor selector, and
a per-rotor motorized-antenna flag so the boom/pattern paths show only for
the rotor carrying the Ultrabeam/SteppIR.

Also in this batch: a keyboard PTT hotkey (hold-to-talk or toggle, reusing
the audio PTT method with a CAT fallback), and TCI spot push to the
panadapter with click-to-fill of the callsign.
