Duncan 96ccaa847e fix(agents): rebind edit ctx to latest persona so drift guard fires

The concurrent-edit drift guard lives in the coordinator, but the
Agents-library route fed it the open-time snapshot: usePersonaActions
stored the clicked AgentPersona in personaToEdit and AgentsView passed
that stale object straight through as ctx.definition. A same-id
personasQuery refresh never rebound it, so both ctx.updatedAt and the
seed-time ref held the old revision, the guard compared equal, and a
one-field edit still clobbered a concurrent writer's untouched fields
via the full-replacement UpdatePersonaInput.

Re-derive the edited persona from live query data by id so ctx advances
with the store while the seed-time ref stays pinned — which is what
makes the guard trip. Deleted-while-editing falls back to the stored
snapshot (editing still drift-guards against last-known state; close and
delete stay reachable). The agent-origin review route
(AgentManagementDialogs) already derives currentPersona from live
personasQuery.data by useMemo, so it was never exposed.
