feat(ci): add supporter verification and auto-hide functionality

Implement BmcSupporterService to verify supporters via BMC API with configurable caching. Add SupporterEmail and HideIfSupporter properties to all controls to automatically hide donation prompts for existing supporters. Replace PNG logo with SVG for crisp rendering at all scales. Add BmcOptions and BmcConfiguration for library-wide settings. Bump version to 1.1.0.
