Fix: Auto-initialize app after accessibility permission grant

Problem:
- When user first launches the app without accessibility permissions,
  the system shows a permission dialog
- After granting permissions, the app was already running but not
  fully initialized
- User couldn't reopen the app (already running) and functionality
  wasn't available

Solution:
- Implemented permission monitoring with Timer (checks every 1 second)
- Deferred app initialization until permissions are granted
- Split initialization into initializeApp() method
- Automatically initialize once permissions are detected

User Experience:
- User grants permission in System Preferences
- App automatically detects permission change
- App initializes and starts working without restart
- Updated alert message to inform user about auto-start

Technical Changes:
- Added permissionCheckTimer for monitoring
- Added initializeApp() for deferred initialization
- Store config and keyMapper as instance variables
- Use Task { @MainActor } for timer callback
- Changed alert style from warning to informational
