* feat: add custom endpoint fields to new profile form
* fix: skip config write tests when PyYAML not installed
The 4 unit tests for _write_endpoint_to_config imported yaml directly
without handling ImportError. Added pytest.importorskip('yaml') at
module level so the entire test class skips cleanly in environments
without PyYAML. Removed redundant per-method yaml imports.

* feat: wire frontend for custom endpoint fields in new profile form
- Add Base URL and API key inputs to the profile create form (index.html)
- Wire panels.js submitProfileCreate() to send base_url and api_key
- Clear new fields on form toggle/cancel
- Add client-side URL format validation (must start with http:// or https://)
- Add server-side URL format validation in routes.py (400 for invalid scheme)
- Add test_api_route_rejects_invalid_base_url() covering the new validation
- Base URL input has placeholder 'http://localhost:11434' per review suggestion
