#401 Refactor multi-ACK localization strings and settings UI

- Updated localization files for multiple languages to change the representation of multi-ACK settings from a string with a placeholder to a simple string.
- Removed unnecessary placeholder definitions for multi-ACK in localization files.
- Adjusted the settings screen to replace the slider for multi-ACK with a switch, simplifying the user interface.
- Updated the Podfile.lock to remove the wakelock_plus dependency.
