- **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.
