Update Dockerfile and Ruby files for improved dependency management and type safety

- Upgraded bundler version from 2.4.5 to 2.5.6 in Dockerfile for better compatibility.
- Updated gem versions for faiss and rails_live_reload to their latest versions.
- Modified Ruby files to enforce strict typing with Sorbet, enhancing type safety across various models and jobs.
- Added type signatures to methods in Inkbunny and FA domain models, ensuring better type checking and documentation.
- Improved job argument handling in Inkbunny jobs, including priority settings for deferred jobs.
- Refactored initialization logic in several models to ensure default states are set correctly.

These changes aim to enhance the overall stability and maintainability of the codebase.
