Fix Settings: stop auto-registering DDNS on cell name change
Unit Tests / test (push) Successful in 7m37s

Two bugs in the pic_ngo availability + auto-save flow:

1. Availability check fired on page load even when cell_name matched
   the currently-registered name — sending unnecessary check requests
   to the DDNS server and showing 'taken' for the user's own name.
   Fix: skip the check when identity.cell_name === loadedCellName.

2. Auto-save triggered DDNS re-registration (release old subdomain +
   register new one) as soon as picAvail became 'available' — without
   the user pressing Accept. This happened because picAvail was in
   the auto-save effect's dependency array, so it re-ran whenever the
   availability check completed.
   Fix: block auto-save entirely for pic_ngo cell name changes; the
   user must press Accept explicitly since re-registration is
   irreversible.
