- Improved handling of nested attributes:
- Replaced old mastery structure with new `rings` and `awakening` assignments.
- Added `new_rings` and `new_awakening` virtual attributes for easier updates.
- Updated `assign_attributes` to exclude `rings` and `awakening` to prevent conflicts.
- Enhanced parameter transformation:
- Introduced `transform_character_params` to process `rings`, `awakening`, and `earring` more reliably.
- Ensured proper type conversion (`to_i`) for numeric values in `uncap_level`, `transcendence_step`, and `awakening_level`.
- Improved error handling for missing values by setting defaults where needed.
- Optimized database queries:
- Added `.includes(:awakening)` to `set` to prevent N+1 query issues.
- Updated strong parameters:
- Changed `rings` from individual keys (`ring1`, `ring2`, etc.) to a structured array format.
- Refactored permitted attributes to align with the new nested structure.
