refactor: centralize auth imports through new client module (#2437)

* refactor(web): centralize next-auth client-side utilities

Create lib/auth/client.ts to re-export all next-auth/react APIs (useSession,
signIn, signOut, SessionProvider) from a single location. This prepares
for future auth provider replacement by isolating the next-auth dependency.
