Add application blacklist mode

[constansino]

Summary

• add an ApplicationListMode setting with Normal, Allowlist, and Blacklist modes
• make blacklist entries pass through scroll, button, and HID++ scroll-hotkey handling while clearing active Mos state
• keep the legacy allowlist preference mapped to the new list mode for existing users
• replace the Application preferences allowlist checkbox with a localized segmented mode selector

Fixes #937.
