feat: replace hardcoded state stubs with real game state in Lua API

Browse source 
IsMounted, IsFlying, IsSwimming, IsResting, IsFalling, and IsStealthed
now query actual GameHandler state (mount display ID, movement flags,
resting flag, aura list) instead of returning false. Add GetUnitSpeed
for player run speed. Fixes addon conditionals that depend on player
movement/mount/combat state.
