Commit Message

fix: return JSON response for unmatched routes instead of plain text (#2457)

## What kind of change does this PR introduce?

Fix

## Summary

Routes behind feature flags (e.g. OAuthServer, CustomOAuth) return chi's
default plain text "404 page not found" when disabled. Register custom
NotFound and MethodNotAllowed handlers on the router so all unmatched
routes return structured JSON errors consistent with the rest of the
API.

Fixes inconsistent `content-type: text/plain` responses when
feature-gated routes (OAuthServer, CustomOAuth) are disabled

## Test plan
- [x] Hit a disabled route (e.g. `/oauth/clients/register` with
`OAuthServer.Enabled=false`) and verify JSON 404 response with
`error_code: "route_not_found"`
