feat: add wizard and physical gear branches to Fabricator

- Split fabricator-recipes.ts into 4 files (all under 400 lines):
  - fabricator-recipes.ts: core/elemental equipment recipes + helpers
  - fabricator-wizard-recipes.ts: 7 wizard branch recipes (staffs, circlet, robe, catalyst, pendant)
  - fabricator-physical-recipes.ts: 9 physical branch recipes (blades, helm, robe, boots, gauntlets, shields)
  - fabricator-material-recipes.ts: 12 material crafting recipes
- Added branch filter UI (All/Elemental/Wizard/Physical) to FabricatorSubTab
- All 902 tests pass
