chore(db): backfill founding_age_years for inhabited bodies (#1000)

Browse Source

Add idempotent MIGRATION_SQL UPDATE to import_economics.py deriving
bodies.founding_age_years via COALESCE(colonial_charter event age,
settlement_wave fallback) per the D-216 amendment.

- Events-first: colonial_charter age_years (authored; 11 bodies).
- Wave fallback: wave_1=600/wave_2=500/wave_3=300/wave_4=100/wave_5=40
  (258 bodies).
- Exclude settlement_wave in (origin, unsettled) -> stays NULL: 4 Sol
  bodies remain NULL (out of player scope, D-236).

Source-canonical via regen-db; 269/273 inhabited bodies now populated.
