feat: add Dockerfile for web/worker/scheduler roles and entrypoint script

Multi-stage build: node:20 builds the SPA, python:3.12-slim runs the app. Same image handles web, worker, scheduler roles via entrypoint.sh's first arg. ffmpeg + unar are baked in for FC-2's transcode + archive paths. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
