Fix PyPI regex and switch Bicep modules to /api/bicep-modules endpoint

catalog.py: Fix HTML parsing regex — pypi-server.i80.dk uses relative hrefs
  like href="pkg-name/" not /simple/pkg-name/. Use simpler <a> text extractor.
modules.py: Replace /call-tool POST (wrong) with GET /api/bicep-modules (new REST
  endpoint added to DevOpsMCP). Simpler, no MCP protocol overhead.
