DCO_Extensions Arma Reforger Mod

Fixes and tuning:

CONVOYS
- A Game Master force move now takes a mounted column OUT of the fight instead of into it: the contact drill (break-contact and the flank assault) yields for mounted groups holding a GM waypoint, keeping only its fire-superiority half, so the column drives and the gunners stay hot. The exhibit was a live column at zero throttle for four minutes while the brain re-issued flank orders at a lone ambush survivor and the stall kicks fought it to exhaustion twice; the moment perception lapsed the standing move resumed on its own, which proved the grip was the drill.
- New m_bConvoyMoraleLock (on): a mounted column under orders never breaks and flees. Any live waypoint counts, not just a Game Master one (commander moves and convoy-link follow waypoints sit below GM priority), and so does membership in a linked convoy; the broken flag still sets, so morale takes effect the moment the column dismounts or its orders end. Owner doctrine: guns hot, keep driving.
- New m_bConvoyDriverRecovery (on): a vehicle with living crew but no conscious driver gets one back while under orders. A body in the pilot seat is ejected beside the vehicle, then a passenger is promoted into the seat using the same server-side placement the GM editor uses; cargo passengers are promoted before gunners, so the guns stay hot, and players are never touched. Closes the gap vanilla cannot: its replacement path needs a get-out first, which CRX force-stay refuses, and a driver who died in the seat blocked everything.

HORN
- The horn mute now starts unconditionally and the config value owns on/off at runtime: the old boot gate meant a server that started with m_bMuteAiHorn false could never enable the mute without a restart, and since the setting DEFAULTS to false, a fresh config shipped with the feature dead. The boot line also told the truth backwards - it printed ENABLED unconditionally whenever the system started - and now reports ENABLED with the patience/hold values, or INACTIVE naming the setting.
- New m_bHornColumnQuiet (on): a convoy follower blocked by his OWN column mate never honks. At the first press the mute checks whether another tracked AI vehicle sits in the driver's forward arc (18m, same group or same DCO convoy id) and suppresses instantly with no patience window, since a follower honking at his lead is the one honk with no audience - the probe sessions showed exactly that profile, pulses at 0-5kph with no contact. Warning honks at civilians, players and strangers are untouched, and it works even with the general mute off.
- Horn mute cycle telemetry under debug: every honk run logs its start with vehicle speed and the driver's lifetime hold count, every earned hold is numbered, every expiry logs the release, and a press observed WHILE a hold is active logs "hold NOT sticking" once per hold - the one signature that separates the engine outracing the frame-cadence zero from a driver eternally re-earning holds. Diagnosis for the "horn is back and not clearing" report; the behavioural fix follows the evidence.
