Auto-install Lua, smooth all panels, airspace overlay + launcher region picker

FlyWithLua auto-install: bridge drops fms-sync/ui-sync/terrain-probe into
X-Plane's FlyWithLua Scripts dir on startup and self-updates (content-compare).
Graceful when no X-Plane / no FlyWithLua. /api/lua/install + status in health.
Desktop app bundles the scripts and passes LUA_SRC_DIR to the sidecar.

Smoothing: shared useEased/useEasedAngle hook (api/ease.js) with render-bail on
settle. VFR steam gauges now interpolate to 60fps instead of stepping at the
~10Hz value stream. MFD ownship no longer vibrates — position/heading eased in a
single rAF loop, follow-pan without animated-panTo pile-up (pauses on range zoom).

Airspace overlay: server/airspace.js loads per-region GeoJSON, classifies
(B/C/D/TMA/CTR/MOA/Restricted/Prohibited/Danger), bbox query, and downloads
regions on demand — FAA (US, key-free) and OpenAIP (Europe, user key). New
AIRSPACE softkey draws chart-coloured boundaries (B blue, C magenta, D dashed),
non-interactive so map-clicks still drop waypoints. Launcher gains a "Lufträume"
section to pick/download regions via the running bridge.
