After the send path emits the bare model id (e.g. "model-a:free"), the
restore/refresh path compared the qualified catalog row value
(@custom:hetmer.net:model-a:free) against the bare state model, so no
row rendered as active/"Selected". Normalize both sides through
_modelPickerOptionIdentity (the same identity used for picker dedup)
and keep the provider equality gate, so exactly one row is restored.
Adds a round-trip regression test (send -> persist -> restore) with a
colon-bearing custom model id asserting exactly one "Selected" row with
the model intact, and updates the #5748 source-assertions to the
normalized comparison.
