AUTO-FIX pauses through the hours (also when pressed outside them); MIDI links without a state judged by the Mac

- AUTO-FIX: tap = pause / resume; a pause lasts through the current or the next auto-fix hours; key says ON TIL,
  OFF / ON <start>, PAUSED TIL; forcing auto-fix on outside the hours is gone
- MIDI: macOS 26 reports every live link's state, so no state there = NO ANSWER; on macOS 14/15 a link put back after
  a drop counts only after 20 s (macOS drops an unanswered one at ~12 s): no more OK/LOST flicker
- WS and SC PROP ignore the rc4 module's harmless warnings, as NA
