fix(chequebook,ctsclearing): surface global stock allocation in UI; fix decided-state check

Receive Stock form now displays the actual highest-allocated serial across
every series (not just silently prefilling the field), so the operator
can see and trust the auto-suggested range start rather than taking it
on faith.

Fixes a real bug where item.decision (which InwardClearingItem.java always
sets to the literal string "PENDING" at creation, never null) was checked
with a plain truthy test everywhere a "has this been decided yet" branch
was needed. Since "PENDING" is a non-empty string, that check was always
true — silently breaking the Decide/View button label, the collapsed
validation summary, the "Awaiting settlement" text, and the decision
dialog itself (which never showed the actual Pass/Return form, even for
still-pending items). Replaced with a proper isDecided() check everywhere.
