[Cleanup] Guard remaining unguarded console.log calls

- core__crud_generic.ts: guard patch result logs (lines 246/252) with
  if (log_lvl) — these fired on every successful patch call
- e_app_sign_in_out.svelte: already committed in previous round
- element_manage_hosted_file_li.svelte: already committed in previous round

All other console.log calls in launcher/lib files confirmed already guarded
via $B2 context check. Remaining unguarded logs are in event handlers
(fire on user action only, not hot render paths) or testing/admin pages.
