fix(journal): the location readout is a FIELD, refresh at the click, and Abandon works

Three fixes from the first connected round.

The location readout is authored EDITABLE (0x16), so it builds as a UiField —
not the UiText its "00.0S, 00.0W" placeholder suggests. The controller resolved
it as text, got null, and threw every write away in silence: Record reached the
model and reached the FILE, and never reached the screen. That is exactly what
was reported, and it is a whole class of bug, so the sweep that found it is now
a test over every element all three controllers bind.

The handlers mutated the model and left redrawing to the next frame's Tick.
Retail's ListenToElementMessage @0x004968D0 ends every one of them in Update()
instead — at the moment of the click. The deferred version happened to work in
the client and made the behaviour untestable and a frame late; the notes-page
tests I had not written until now fail against it.

Abandon is wired. "Retail's abandon path is a contract-registry command we have
not ported" was wrong — it is game action 0x0316 with a single contract id, and
ACE replies with the 0x0315 delete QT3 already handles. Nothing is removed
locally, so a refusal leaves the quest visibly intact rather than vanishing it
optimistically and having it reappear on the next full table.
