Implements the Groups & Routes admin page with a client-side RouteManager
component (add/delete sync routes via fetch), server-side groups page that
pre-fetches groups/routes from the API, and Next.js Route Handler proxies
for /api/routes (GET, POST) and /api/routes/[id] (DELETE). Adds a custom
jest environment that polyfills Node 18+ native fetch into the jsdom sandbox
so tests can use jest.spyOn(global, 'fetch').

Replaces DisconnectReason enum import with type-only WASocket import and
uses 401 directly instead of DisconnectReason.loggedOut. Baileys is an ES
module that cannot be executed in Jest's CommonJS mode, so removing the
value import (keeping only type imports) prevents ts-jest from trying to
execute the module.
Also updated session-pool.test.ts to verify end() is called with the
expected Boom error object instead of undefined.
