refactor: move source tree into work/, multi-stage Docker build, fix satpass

- Move all application source (meshai/, dashboard-frontend/, tests/,
  config/, docs/, Dockerfile, etc.) into work/ directory
- Add Node.js multi-stage build to Dockerfile for frontend compilation;
  remove compiled static assets from git tracking
- Fix satpass missing time windows: consolidation was splitting wire on
  newline and only putting line 1 in event.title, dropping the time
  window line that the composer uses for precomposed broadcasts
- Fix satpass burst flooding: stagger consolidation timers (+60s per
  pending pass) so Central batch publishes don't blast the mesh
- Update CI workflow build context to work/
- Anchor lib/ and data/ gitignore patterns to repo root to prevent
  false matches on nested directories
- Add dashboard-frontend/node_modules/ to .dockerignore
