New tables for the celestial body hierarchy below system level:
- bodies: planets, moons, gas giants, asteroid belts, oort clouds
with physical properties, settlement data, and cultural overrides
- stations: orbital/surface facilities with type, population,
docking class, and gate infrastructure flag
Naming convention: GJ-{n}b (planet), GJ-{n}b-1 (moon),
GJ-{n}b-S1 (station), GJ-{n}-oort (oort cloud).
Self-referential parent_body_id for moon→planet relationships.

Replaces flat star_systems table with 7 normalized tables: star_systems,
system_gates (with hop_distance_from_gateway), system_history,
historical_events (1:N), system_economy, system_factions, system_culture.
Primary key is now the GJ astronomical ID (e.g., "GJ 244A") — S-number
identifiers removed entirely. The astronomical_id column is dropped as
redundant. Database moved to server/data/systems.db (ships with game).
10 core systems fully populated with structured data.
