Release v0.6.1 - Bug fixes and enhancements

New Features:
- Auto-update system with configurable check frequency
- Updates tab in settings with manual check button
- Localhost development mode bypasses license validation
- Extended general settings (address, contact, social media)
- Pricing settings split into subtabs
- Guest ID/passport encryption using AES-256-CBC
- Guest auto-creation from booking form

Bug Fixes:
- Fixed Booking admin issues with auto-draft status
- Fixed guest dropdown loading in booking form
- Fixed booking history display on Guest edit page
- Fixed service pricing meta box (Gutenberg hiding meta boxes)

Changes:
- Admin submenu reordered for better organization
- Booking title shows guest name and dates (room removed)
- Service, Guest, Booking use classic editor (not Gutenberg)
- Settings tabs flush with content (no gap)
