refactor: replace sveltekit-og with native Satori implementation

- Remove @ethercorps/sveltekit-og and bits-ui dependencies
- Implement direct Satori + Resvg rendering pipeline
- Add OgImage.svelte component for template generation
- Create /internal/ogp preview page for development
- Load fonts from node_modules via fs for production compatibility
- Add 2s startup delay before OG image regeneration
