Add Open Graph and Twitter Card meta-tags for link previews

Replace PathResourceResolver SPA fallback with SpaController that injects OG/Twitter meta-tags into cached index.html template. Event pages get event-specific tags (title, date, location), all other pages get generic fete branding. Includes og-image.png brand asset and forward-headers-strategy for proxy support.
