Feat/global hotkey settings

[abhaymundhara]

Description

Added a customizable global hotkey feature to the Settings dialog. Users can now record, save, and reset their preferred keyboard shortcut for activating OpenWork. The feature includes real-time recording, validation, error handling, and animated toast notifications for user feedback.

Key additions:

• Interactive hotkey recorder with live key capture
• Save/Reset functionality with persistence via IPC
• Toast notifications with slide-in animations for success/error states
• Cross-platform support (CommandOrControl maps to Cmd on macOS, Ctrl elsewhere)
• ESC key to cancel recording
• Visual feedback during recording state
• Input validation and conflict detection
