fix: prefer exact path match over parameterized match for method checking

[themavik]

Summary

• Fix route matching to prefer exact path matches over parameterized matches when checking HTTP methods
• Previously, a POST to /VerifiedCallerId/Verification/ would match GET VerifiedCallerId/:phone_number and return 405

Root Cause

The router matches parameterized routes before checking for exact matches at the same path level. This causes incorrect 405 responses when an exact match exists for a different method.

Testing

• Added test case for the reported scenario

Fixes #2547
