chore(docker): update Dockerfile for Next 16, drop duplicate lowercase dockerfile

Browse Source 
- update stage comments to Next 16; note Turbopack default build
- npm ci --no-audit --no-fund for faster reproducible install
- add HEALTHCHECK (referenced by docker-compose, previously missing)
- parametrize node version via ARG NODE_VERSION
- remove duplicate case-variant 'dockerfile' (collided with 'Dockerfile'
  on case-insensitive FS, would be two files on Linux/Coolify)

Verified: docker build + run, all routes 200, multi-domain Host routing,
canonical in <head>, container healthcheck reports healthy.
