kyber-server: add interactive map rotation selection

Shows a numbered menu of 12 known SWBF2 maps (Galactic Assault, Planetary
Battles, Starfighter Assault) during install. Selected maps are encoded as
base64 JSON and written to KYBER_MAP_ROTATION in .env.

Map IDs decoded from maprotation.hive binary: Geonosis, Kamino, Endor,
Tatooine, Death Star II, Starkiller Base, Crait, Hoth, Fondor (space).
