refactor: Remove unused files and dependencies to streamline the application

- Deleted the Dockerfile and several helper files (ApplicationHelper, LearningsHelper, StaticPagesHelper) as they are no longer needed.
- Removed application job and mailer files to simplify the codebase.
- Eliminated PWA-related files including the manifest and service worker to reduce complexity.
- Updated Gemfile to comment out unused gems (jbuilder, kamal, solid_queue, solid_cable, rubocop-rails-omakase) and reflected these changes in Gemfile.lock.
- Adjusted application layout to use the correct stylesheet link for improved consistency.
