fix: add sqlite-dev to container builder stage

database-mcp FFI links against libsqlite3 — Wolfi base image needs
sqlite-dev package for the Zig compilation to succeed.

Also: DNS configured on Cloudflare for boj-server.net:
- boj-server.net -> 209.42.26.106 (VPS, proxied)
- api.boj-server.net -> 209.42.26.106 (VPS, proxied)
