Added full keyboard support - arrow keys and WASD for panning, Q/E for zooming.

Visual improvements were the star of the show today. Added a parallax starfield with subtle glow effects in the background - really sells the space vibe. Added hover glow for selectable items so it’s clear what you can interact with.

Ships got a lot of love: they now rotate toward their target on liftoff, have thrust particle effects during flight, ramp down thrust when arriving at orbit, and the orbit-to-path transition is smoother. Also optimized the orbit path to landing pad routing.
