Pinterest-like app for saving images, videos, quotes, and embeds.

Features:
- Go backend with PostgreSQL, SSR templates
- Console-based admin auth (login/logout via browser console)
- Item types: images, videos (ffmpeg transcoding), quotes, embeds
- Media stored as BLOBs in PostgreSQL
- OpenGraph metadata extraction for links
- Embed detection for YouTube, Vimeo, Twitter/X
- Masonry grid layout, item detail pages
- Tag system with filtering
- Refresh metadata endpoint with change warnings
- Replace media endpoint for updating item images/videos
