feedback1d WN: a field opened after 暴鸰's drop draws it without its bomb (UnitInfo.form)

The bomb-less mode lived only in the client that saw the fx 'phase' event. UnitInfo now
carries an enemy's recorded mode (unit.form, set by kitBombd at the release), and the
renderer keeps it on the unit info, so a field watched or rejoined later starts on the
*_2 clips.
