feat(app/docker): integrate committed packs and optimize embedding provider

Configure embedding provider with 4 workers, batch size 64, and caching for better throughout. Prioritize loading local committed packs (faction-politics, wisdom-scrolls) over HuggingFace downloads, suppress progress bars, and copy packs into Dockerfile. Update READMEs to fix dataset name references. Reduces startup time and ensures essential packs are always available locally.
