Admin gets an editable name input + emoji picker at the top of
/collective/manage. Enter / blur / Save button all flush the PostgREST
UPDATE; Esc reverts to the persisted value. The response payload feeds
both $currentCollective and $userCollectives so the sidebar updates
without reload. Members and guests see no editing affordances at all
(the section is admin-gated; UPDATE policies were already in place from
Fase 2a so no migration is needed).
MC-01a: Ana renames + picks a new emoji, reload preserves both, DB
reflects the change. MC-01b: Borja never sees the editable fields.
