feat(certificates): per-customer document preferences (CHUNK 1/4)

Customers can now pick which shipping-time documents they actually want
instead of the shop remembering it per account. Four booleans on
res.partner (only shown on companies, not contacts):

  x_fc_send_coc              (default True)  Certificate of Conformance
  x_fc_send_thickness_report (default True)  Thickness readings
  x_fc_send_packing_slip     (default True)  Packing slip PDF
  x_fc_send_bol              (default False) Bill of Lading

Surfaced in a "Plating Documents" page on the customer form.

Two downstream gates:

1. fp.notification.template._collect_attachments() now reads the flags
   when attaching CoC / thickness / packing / BoL PDFs to the shipping
   confirmation email. Flags missing on the partner (e.g. legacy
   customers) fall back to the original defaults so nothing regresses.

2. mrp.production.button_mark_done() only auto-creates the quality
   documents the customer wants. A customer that unchecks both CoC and
   thickness gets zero certs auto-generated — shop can still create
   them manually if needed.

Note: today a standalone thickness-only report template doesn't exist,
so when a customer asks for thickness only (CoC off, thickness on) the
dispatcher still attaches the CoC PDF (which carries thickness data)
but with CoC creation gated off. A dedicated thickness-only template
is a follow-up.
