Fix 3rd autopilot UI (Bezel APController) + wire dead PATHWAY/APTSIGNS keys

Line-by-line control audit. APController (the MFD left-bezel autopilot mode
controller) still decoded the unreliable autopilot_state bitfield — the same bug
already fixed in AutopilotPanel and KAP140, missed in the third AP UI. Now reads
per-mode *_status datarefs so every mode key lights correctly.

PATHWAY and APTSIGNS softkeys were dead (sim-mirror only). PATHWAY now draws the
flight-plan route on the synthetic-vision terrain; APTSIGNS toggles the runway
labels. Threaded via App svtOpts → PFD → SVT.
