Performance: OPcache, gzip, font subsetting, lazy-loaded pages

- Enable PHP OPcache in Docker (256MB, dev-friendly settings)
- Enable gzip compression in nginx + immutable caching for /build/ assets
- Reduce fonts to latin-only subsets (from 28 files to ~6)
- Lazy-load Vue pages via dynamic imports (D3 no longer loaded on login)
- MetroMap chunk split out separately (62KB only when needed)
