feat(GRO-653): add portal session middleware and server-side audit logging (#300)

* feat(GRO-653): add portal session middleware and server-side audit logging

- Add validatePortalSession middleware that reads X-Impersonation-Session-Id header,
  queries impersonationSessions, and sets portalClientId + portalSessionId on the context
- Add portalAudit middleware that logs all portal requests to impersonationAuditLogs table
- Apply both middlewares to the portalRouter
- Replace all getClientIdFromSession() calls with c.get("portalClientId")
- Remove getClientIdFromSession() helper and inline session checks in waitlist routes
- Consistent session.expiry > new Date() check across all routes

* fix(GRO-653): remove unused sessionId variable and and import

Fix lint errors flagged by QA:
- Remove unused `sessionId` variable from PATCH waitlist handler
- Remove unused `and` import from portal.ts
