res.partner.x_fc_default_coc_contact_id (single Many2one) becomes
x_fc_default_coc_contact_ids (self-referential Many2many 'Default CoC
Contacts') so a customer can list several contacts who need the CoC.
- res.partner: M2m field (rel fp_default_coc_contact_rel) + many2many_tags.
- Cert: contact_partner_id (primary addressee printed on the cert) is set to
the FIRST CoC contact at job creation + lazy-filled at issue.
- Send: action_send_to_customer pre-fills the email composer with ALL the
customer's CoC contacts (primary + the rest), falling back to the company.
- fp.job cert-default resolution + the action_issue gate wording updated.
- Migration 19.0.10.2.0: copies each partner's old single value into the new
M2m, then drops the orphaned column.
Deployed + verified on entech: migration copied 2 existing values, old column
dropped, field is M2m, send pre-fills all contacts. entech-only part_line_ids
/ multi-part resolver preserved.
