fix: Phase 8a - fix users.update function call (24 -> 23 errors)

Fixed incorrect function call to users.update by removing extra fetch argument.

The issue: settings page was calling users.update(fetch, userId, updateData)
but the function signature is users.update(userId, updateData).

The fetch parameter is not needed - the users.update function uses the global
fetch internally via userAdapter.

Changes:
- src/routes/settings/+page.svelte:
  - Removed fetch argument from users.update call
  - Changed from: users.update(fetch, account.userId, updateData)
  - Changed to: users.update(account.userId, updateData)

Result: 24 → 23 errors (-1)
