fix(fusion_plating): bug review fixes + progress/net-terms invoicing + formal CoC rebuild

Bug review fixes (found by code review + live QWeb error):
- report_fp_sale.xml: product_uom → product_uom_id (Odoo 19 renamed;
  was raising KeyError during PDF render, blocking all sale-order prints)
- mrp_production.button_mark_done: add idempotency guard on delivery
  auto-create (was duplicating on every re-close)
- fp.certificate._compute_batch_ids: use empty recordset instead of
  False for Many2many computed fields
- fp_notification_template._collect_attachments: collapse attach_quotation
  + attach_sale_order into a single render so email doesn't double-attach
  the same PDF
- fp.operator.certification: SQL unique on computed state was unreliable;
  added explicit `revoked` boolean, made state pure-compute, replaced
  SQL constraint with @api.constrains that checks active-only uniqueness;
  has_active_cert now reads revoked + expires_date directly (no stale
  stored state between nightly recomputes)

Two missing invoice strategies implemented + 1 pre-existing deposit bug fix:
- Progress Billing: new x_fc_progress_initial_percent field on sale.order;
  _create_progress_initial_invoice bills the configured % on SO confirm
  via down-payment wizard, _create_final_balance_invoice bills the
  remainder on delivery
- Net Terms: no invoice on confirm; full invoice auto-created when
  fusion.plating.delivery.action_mark_delivered fires
- Fix for deposit (pre-existing, silent): sale.advance.payment.inv
  reads active_ids at wizard-create time, not on create_invoices();
  context was being set on the wrong call, so every deposit attempt
  raised "Expected singleton" and message-posted to chatter instead
  of actually invoicing
- New fusion_plating_invoicing/models/fp_delivery.py hooks
  action_mark_delivered to dispatch final invoice for progress/net_terms
- fp.direct.order.wizard + SO form surface the progress_initial_percent
  field (conditional on strategy)

Report styling cleanup:
- Hide DISCOUNT column from sale + invoice landscape reports unless at
  least one line has a non-zero discount; colspan auto-adjusts
- Replace hardcoded #0066a1 in all reports with company.primary_color
  driven by doc.company_id → company → user.company_id fallback chain,
  with #1d1f1e as ultimate fallback; new .fp-header-primary class
  exposes the colour for inline section headers (CARGO DESCRIPTION,
  PAYMENT DETAILS, OPERATOR SIGN-OFF, etc.) so they retint with the
  company theme without template edits

Certificate of Conformance — formal ENTECH-style rebuild:
- New res.company fields: x_fc_owner_user_id (default signer, sig from
  hr.employee.signature), x_fc_coc_signature_override (manual upload),
  x_fc_{nadcap,as9100,cgp}_logo + _active toggles for accreditation
  badges
- New res.config.settings section "Fusion Plating" exposing the above
  as configurable blocks; manager-only menu under Configuration →
  Fusion Plating Settings
- New fp.certificate fields: nc_quantity, customer_job_no,
  contact_partner_id (child contact for Name / Email / Phone block)
- New report_coc_en + report_coc_fr templates (primary): custom header
  (company contact | accreditations | company logo), bilingual labels
  per variant, customer info block with customer logo, 3-column cert
  info table, 6-column line-item table (Part # | Process | Customer
  PO | Shipped | NC Qty | Customer Job No.), signature image + bordered
  certification statement, footer "Fusion Plating by Nexa Systems"
- Legacy report_coc + report_coc_portrait kept for existing portal-job
  bindings (no behaviour change)
