fix: remove circular dependency by moving useLastUsed hook to auth features (calcom#24552)

- Move useLastUsed hook from packages/lib/hooks to packages/features/auth/lib/hooks
- Update imports in SAMLLogin.tsx and login-view.tsx
- Remove cross-package tsconfig include of ../trpc/types/router.d.ts from packages/lib/tsconfig.json

This fixes the issue where the IDE was unnecessarily initializing packages/ui/tsconfig.json
when navigating to definitions in packages/lib. The hook was importing from @calcom/ui/classNames,
creating a circular dependency since packages/ui depends on packages/lib.

By moving the hook to packages/features/auth where it's actually used, we eliminate the
circular dependency without adding tailwind dependencies to packages/lib.
