feat: hive setup data model and API (Beute L1)

Each colony can now hold its hive setup (Ist-Zustand) as validated
JSON with an append-only change log:

- catalog: hive systems and part types with dimensions, placement
  rules and state fields; Liebig-Zander 10 seeded with fixed ids
  (owner's equipment incl. Bausperre, Futterzarge, Nassenheider)
- pure domain module (operations, validator, derived facts) with
  shared JSON fixtures the frontend runs too
- API: catalog (hive-systems:manage), setup create/change/history/
  state at a day (colonies:read/update), 409 HIVE_CONFLICT with the
  current state, idempotent writes, HiveChanged event
- inspections can carry hive ops saved in the same transaction
- backup export/import of the new tables (backup wins per colony)
- docs: ARCHITECTURE section 13, Annahmen 95-100
