Anso ca5a930c68 refactor(backend): extract authMiddleware and introduce createApp factory (phase 2) (#732)
Phase 2 of the index.ts refactor. Pulls the auth middleware and session
cookie issuers into their own module, and introduces the app.ts factory
that owns the first nine steps of the canonical middleware pipeline.

New modules:
- middleware/auth.ts: authMiddleware, issueSessionCookie,
  issueMfaPendingCookie, clearMfaPendingCookie
- app.ts: createApp() factory installing trust proxy, helmet, cors,
  compression, cookieParser, rate limiters, conditionalJsonParser, and
  nodeContextMiddleware. A header comment documents all 16 canonical
  middleware steps and where each currently lives.

Changes:
- middleware/authGate.ts: createAuthGate factory removed; authGate now
  imports authMiddleware directly (the factory existed only to avoid a
  circular import while authMiddleware lived in index.ts).
- services/DatabaseService.ts: added API_TOKEN_SCOPE_TO_ROLE map so the
  auth middleware no longer inlines a stringly-typed record.
- index.ts drops ~260 lines; auth routes, authGate, auditLog,
  apiTokenScope, remaining routes, static serving, and the error handler
  continue to be registered there until their respective phases.
- vitest.config.ts bumps testTimeout to 30s and hookTimeout to 45s so
  fork-pool workers have enough headroom to ts-node-transform the
  growing module graph under CPU contention (64 workers each import the
  full Express stack in beforeAll).

Code review fixes: use getErrorMessage() util in the auth catch block
instead of inline cast; promote the scope-to-role map to a typed
module-level constant.
