fix: correct 4 factual inaccuracies in README

- Fix webhook route: /hooks/<uuid> → /webhook/{uuid} (matches routes.go)
- Fix CGO claims: acknowledge mattn/go-sqlite3 transitive dep requires CGO at build time
- Fix database architecture: distinguish current single-DB from planned Phase 2 per-webhook split
- Fix static file descriptions: Bootstrap CSS/jQuery JS → actual style.css and app.js
