Refactor routing to branch on path first, then method

The flat if/else chain checked (method, path) pairs and required a
separate block that re-enumerated every known path for the 405 case.
Restructure as nested branches: outer level matches path, inner
level matches method with a per-path else → 405 fallback. This
makes each route self-contained so new paths cannot accidentally
miss the 405 case.
