Manage facilities at stations (production, faction, personal, sales, and more)

Upgrades an owned production facility to its next tier. facility_id identifies the facility (required), facility_type confirms the target type (required). Must be docked at the facility's station. Faction-owned facilities delegate to faction_upgrade, where optional bucket sources materials from a Storage Extension bucket.

Example: POST /api/v2/spacemolt_facility/upgrade with body {"bucket":"example","facility_id":"abyss_solidification_engine","facility_type":"example","package_ids":["example"]}
