fix(jobs): Finish & Next bulk-moves all parts, no more "click N times"

User feedback: operators with small parts (e.g. valve bodies) batch
them through the whole recipe. The previous behavior — Finish & Next
raising "use Complete 1 → Next or Move..." when qty>1 — forced N
clicks for a workflow that's naturally one click.

Change: _fp_record_one_piece_auto_move now ALWAYS bulk-moves
qty_at_step parts to the next step in one move record, regardless of
whether the qty is seed-only (first / paperwork step) or real (parked
from an upstream move). Audit trail is preserved (one move row per
finish), operator gets one click.

Three buttons now map cleanly to the three workflows:
  - Finish & Next: bulk all parts forward, finish, auto-start next
  - Complete 1 -> Next: streaming flow, move 1 part, stay open
  - Move...: explicit qty + destination wizard for partial batches

Verified end-to-end on entech: seed qty=6 + real-incoming qty=6 both
move forward in a single click each.
