Quiet no-op particle setting clicks and show entry particle counts

Clicking a step past the minimum or maximum, or setting an unchanged
value, now does nothing instead of showing the budget message, and
changes that lower a slot's particles are allowed even over budget.
Entries show their particles per tick in the slot editor list, and the
entry editor's paper shows the edited entry's share.
