BP_PlayerCharacter (Character-based): first-person camera, WASD
movement + A/D turning (same input scheme as the ship), SuitOxygen
stat that depletes each tick, clamped at 0. Not auto-possessed yet --
that's the ship exit/enter transition (next task). Placed one
instance in L_TestFlight near the ship spawn.
Also reverted level gravity to default (-980): FloatingPawnMovement
(ship) never reads world gravity regardless of its value, but
CharacterMovementComponent (this character) needs real gravity to
walk normally. Zero gravity was an unnecessary leftover from Phase 0
that would have broken on-foot movement.
