feat(sticker): per-box render loop + Notes override hook

Inner sticker template gains two parameters that outer templates
pre-set:

  _qty_total — total qty for the line/job. Inner wraps the body
    in t-foreach="range(int(_qty_total or 1))" so a qty=5 line
    produces 5 consecutive single-box stickers. Qty row in the
    body switches from "5" to "1 / 5", "2 / 5", ... "5 / 5".
    When _qty_total is missing/0/1, the Qty row keeps showing
    the plain integer (regression-free).

  _notes_content — Notes column source. Existing inner code
    hard-read _line.name; new code accepts an outer override
    and falls back to _line.name. External outers don't set it
    (unchanged behaviour); the new Internal outers (Task 4+5)
    pre-set it to x_fc_internal_description.

Defaults template initialises both new vars to False so the
inner's "outer-supplied OR fallback" pattern doesn't NameError
when called from existing outers that haven't been updated yet.

Verified regression-free: fp.job 2635 (qty=1) renders identically
to its pre-Task baseline — Qty row shows plain "1", Notes from
line.name as before.
