Revamp navigation with org switcher and user menu, fix passkey login

Navigation changes:
- Add org-switcher dropdown to sidebar showing user's orgs
- Add user-menu dropdown with account settings and sign out
- Make nav items dynamic based on org context
- Move performance page to /dashboard/[slug]/performance
- Add reports placeholder page at /dashboard/[slug]/reports
- Remove admin link from sidebar (separate layout)
- Update mobile nav to match sidebar changes
- Install shadcn dropdown-menu and popover components

Auth fix:
- Mark login request as completed after passkey verification
- Previously passkey auth didn't complete the login flow, requiring
  unnecessary email verification
