feat: bake bicep catalog into image; fix dict-based modules parsing

- Remove all DevOpsMCP/aiohttp runtime deps from BicepModuleCatalog
- BicepModuleCatalog.load() reads bicep_modules_catalog.json from disk at startup (sync)
- Fix _load_catalog: catalog uses dict {path: {versions, schema}} not a list
- server.py: call BicepModuleCatalog.load() synchronously, not via asyncio.gather
- Dockerfile: COPY bicep_modules_catalog.json into both builder + runtime stages
- Health endpoint now reports bicep_modules: 27

Verified locally: make run-quick → health returns pypi_packages:40 bicep_modules:27
