Update .gitignore, Gemfile, and various job classes for improved functionality

- Added '*.notes.md' and '*.export' to .gitignore to prevent unnecessary files from being tracked.
- Refactored job classes in the Domain::Fa module to enhance logging and job enqueuing processes, including:
  - Improved logging messages in Domain::Fa::Job::Base for better clarity.
  - Added support for a new 'enqueue_favs_scan' option in user job processing.
  - Enhanced the FavsJob to utilize active fav post joins and added a 'removed' flag for better management of favorites.
- Updated user and post models to include scopes for active favorites and improved error handling in user creation.
- Enhanced the page parser to support new formats for favorites pages and added tests for these changes.
