v1.12.0 — takeoff & landing phases on the marker

Every leg gains a 10-min takeoff phase at the origin and a 10-min
landing phase at the destination, each weather-scaled up to 2x via a
monotone condition rule (Clear < Cloudy < Rain < Fog). Single
composition in lib/sim/movement.ts: BASE_PHASE_MS, phaseFactor,
MAX_PHASE_FACTOR, legPhases; arrivalTimeFor and progressAt route
through it (progress is now piecewise — hold at origin / linear cruise
/ hold at destination), so engine arrival gate, client position/fuel
recompute and the job expiry floor all agree. Phases burn no fuel.

Marker shows the current phase next to the status in the popup
(mapData derives it from departureSimTime + clockMs; new
data-testid=plane-phase sibling). plane-status keeps the raw status.

Tests: movement.test.ts (phaseFactor bounds/monotonicity, origin-vs-dest
composition, piecewise progressAt), engine.test.ts (deleted local travelMs
mirror — all ~18 fixture clocks use the real composition), seed.test.ts
(phase-inclusive expiry floor mirrors). New e2e/phases.spec.ts asserts
'taking off' at the origin gate and 'landing' at the destination gate on
EDDF→LEMD using the same legPhases boundaries as the engine.
