feat(15-02): update MCP OAuth and MCP middleware for OIDC

- Replace verifyPassword with getAuth in OAuth authorize routes
- Replace login form with consent-only form (no credential fields)
- Remove getUserCount bypass from MCP auth middleware
- GET/POST /authorize redirect to /login if no OIDC session
