- Update all POST endpoints in tests from /api/v1/{weapons,characters,summons} to /api/v1/grid_{weapons,characters,summons}
- Update custom action endpoints (update_uncap, resolve, update_quick_summon) to use grid_ prefix
- Fix routes configuration to use :create instead of :post in resources definition
- Add custom DELETE routes that accept ID in request body
All 44 grid controller tests now pass with the new endpoint naming convention.
