feat(core): add page title support and PageContext

- Add abstract title property to PageComponent base class
- Create PageContext class to expose page metadata to templates
- Add property binding support for child components via prop-* attributes
- Register authorisation services in Spry module
- Add add_resource method for static resource registration
- Implement title property across all demo and example page components
- Make UserIdentityProvider public for external access
