feat(importing): Add head bone tail positions and improve armature modification logic

Browse Source 
- Add 74 head bone tail position definitions to better_fbx_bone_tails dictionary for improved bone orientation accuracy
- Create backup file modifyarmature_bak.py for version control
- Conditionally apply delete_accessory_bones() only for Koikatsu armature type (C)
- Add cf_J_hitomi_tx_R and cf_J_hitomi_tx_L to preserved bones list
- Implement conditional bone reorientation logic for non-Koikatsu armature types (A/B/D)
- Simplify leg bone tail relocation by removing better_fbx data check and always applying standard z-alignment
- Improve armature modification workflow to handle different armature types with appropriate bone processing strategies
