refactor: replace co-authored setting with flexible common config snippet feature

- Replace single "disable co-authored" checkbox with universal "common config snippet" functionality
- Add localStorage persistence for common config snippets
- Implement deep merge/remove operations for complex JSON structures
- Add modal editor for managing common config snippets
- Optimize performance with custom deepClone function instead of JSON.parse/stringify
- Fix deep remove logic to only delete matching values
- Improve error handling and validation for JSON snippets
