refactor: remove dead code and dedupe redundant utilities (#1230)

* refactor: remove 42 unused localization keys and regenerate l10n

* refactor: remove dead tmux methods and unused res constants

* refactor: drop unused comparator/sudo-password methods and dedupe shellSingleQuote

* refactor: replace deprecated EquatableMixin and complete tmux barrel export

* test: update tests after removing dead tmux and comparator methods

* fix: use 'extends Equatable' instead of 'with Equatable' in Disk
