[Bug]: model registry validator accepts padded names and config IDs

System Info

Platform-independent AutoDeploy registry validation.

Reproduction

validate_models() checks name and config_id with .strip() only to determine whether they are non-empty, but then retains the original untrimmed values. Entries such as name: "model" and name: "model ", or config_id: "default" and config_id: " default", therefore pass validation as distinct identifiers.

These invisible leading/trailing characters can bypass duplicate checks and later produce lookup mismatches.

Expected behavior

Registry identifiers should reject leading or trailing whitespace.

Actual behavior

Padded non-empty strings are accepted.

Proposed fix

Reject surrounding whitespace in name and config_id, with focused validator regression tests.

Start at the validate_models() entry point and inspect the focused validator tests or their surrounding test module. Add regression coverage showing that leading or trailing whitespace in name and config_id is rejected; done means padded identifiers no longer pass validation.
