feat: migrate from npm to bun and fix analytics map height

Switch package manager and runtime from Node.js/npm to Bun across
Docker, CI, and scripts. The SQLite driver remains better-sqlite3
due to Next.js Turbopack being unable to resolve bun:sqlite during
build-time page pre-rendering.

Also fix the world map not rendering in the analytics page — the
overflowX wrapper added for mobile broke the flex height chain,
collapsing the map to 0px.
