Message:

REST API: Fix namespace shadowing issue in route matching logic.

Following [47260] a namespace such as "test-ns" prevents any namespace such as "test-ns/v1" from being found when matching routes.
While not best practice, this was an unintentional back-compat break; this patch restores the original behavior.

Props david.binda, TimothyBlynJacobs.
Fixes #48530.
