style: Update RuboCop config and remove frozen_string_literal comments

- Updates .rubocop.yml with the latest user-provided configuration,
  including explicit `Style/FrozenStringLiteralComment: Enabled: false`.
  - Obsolete cops (RSpec/FilePath) and cops from extensions that
    failed to load in the environment (FactoryBot, RSpec/Capybara)
    have been commented out in .rubocop.yml to allow RuboCop to run.
- Removes `# frozen_string_literal: true` comments from all Ruby files
  and relevant script/config files.
- Applies auto-corrections from the active RuboCop rules.
