Updates the existing Czech localization PR onto the latest upstream master and keeps all previously prepared settings translations:

• Touch and activation → Dotyk a aktivace
• Navigation → Navigace
• Move focus to new windows → Přesunout focus do nových oken
• Apps → Aplikace

Also adds Czech translations for the new Backup and restore screen, including export/import actions, summaries and status messages.

The lint safeguards were updated as part of the same localization change:

• exact MissingTranslation suppressions for the four settings resources
• exact suppressions for each Backup and restore string instead of a broad settings_backup_ prefix
• exact suppressions for the two rotor sound strings instead of a broad individual_sound_rotor_ prefix

This keeps future newly added strings visible to lint instead of silently hiding them behind prefix-wide suppressions. The lint baseline was checked for these resources and contains no matching entries.

Validated on the updated head: build, unit tests, and lint all passed.
