Invalid MetadataUrl accepted for OData client without error

[retran]

Description

CREATE ODATA CLIENT accepts clearly invalid metadata URLs (like 'not-a-url') without error. It treats any string as a local file path and only warns at runtime.

Steps to Reproduce

./mxcli -p project.mpr -c "CREATE ODATA CLIENT MyModule.BadClient (MetadataUrl: 'not-a-url', TimeoutInSeconds: 30)"

Result: "Created odata client: MyModule.BadClient" — no validation error.

Expected

Error or warning at creation time if the URL is obviously malformed (no scheme, no dots, etc.).

Severity

Low — creates broken configuration silently; only discovered at runtime.
