v2.1 — Fix localization via ArchiveXL .xl file

- Use string keys (crystal_katana_name) instead of LocKey# in YAML
- Create crystal_blades.xl to register translation JSONs with ArchiveXL
- Translation JSONs with primaryKey:0, secondaryKey matching YAML refs
- EN + DE translations in proper ArchiveXL format
- Remove old r6/loc/ approach (didn't work)
- Names should now resolve correctly in-game
