Add roll, Job Card and quotation-estimate fields; lay Makap fields out in tabs

- Batch gets roll details (stage, width, length, micron, net/gross kg,
  supplier lot, machine, Work Order) so each roll is a traceable batch (B3).
- Job Card gets operator output and waste capture on its first tab, with a
  derived waste % and a required reason whenever waste is entered.
- Quotation Item can cost a line from an estimating BOM: material grossed up
  for expected waste, BOM operating cost, set-up and cylinder charge, with
  the resulting margin shown against the quoted rate (M4).
- About 120 fields used to stack after amended_from with no sections. They
  now sit in a "Makap" tab per form (a section on child rows) with labelled
  sub-sections, and positions are updated on migrate (m1).
- Tooling Readiness is read-only: it is derived from the cylinder register.
