feat(ui): implement comprehensive dashboard and enhance frontend experience

This commit introduces a major overhaul of the user interface, transitioning from a basic structure to a feature-rich dashboard system. Key improvements include:

- **Dashboard Implementation**: Added a complete dashboard routing system with dedicated pages for Overview, Bookings, Customers, Zones, Billing, and Settings.
- **New UI Components**: Introduced a variety of high-quality components including `AnimatedList`, `FloatingDock`, `HoverFeatureCards`, `VideoPlayer` (with ambient glow effect), `PinnedList`, and `DashboardMockup`.
- **Enhanced Dashboard Features**:
    - Integrated real-time KPI cards and activity timelines.
    - Implemented a multi-view calendar system.
    - Added customer and booking management interfaces with filtering and search capabilities.
    - Added a zone/location management view with map integration.
- **Branding & Visuals**: Updated the application with new SVG logos (horizontal and vertical variants) and implemented dark/light mode optimized branding.
- **Internationalization**: Expanded i18n support with comprehensive Czech and English translations for the new dashboard and integration modules.
- **Integration Tools**: Added a new `IntegrationModal` allowing users to easily embed Bookra widgets via HTML, React, SolidJS, or PHP.
- **Backend Support**: Updated the booking service to provide comprehensive dashboard summary data, including historical booking records for charts.
