feat(fusion_plating): Tier 2 (quality + audit) and Tier 3 (business) features

Tier 2 — Quality & audit readiness:

- T2.1 SPC on thickness readings (fp.certificate)
  - spec_min_mils / spec_max_mils auto-pulled from coating config on create
  - Computed: std_dev_mils, min/max, cpk, cpk_status (incapable/marginal/
    capable/excellent/insufficient)
  - Western Electric trend rules (rule 1: any point beyond 3σ; rule 4:
    8 consecutive on one side of mean) → trend_alert + explanation
  - New SPC group on certificate form with badge-coloured indicators

- T2.2 Operator certification enforcement (fp.operator.certification)
  - Per (employee, process_type) records with issued/expires dates,
    training record attachment, revocation workflow
  - State auto-computed: active → expired when date passes
  - MrpWorkorder.button_start() blocks with UserError if current user's
    linked hr.employee lacks an active cert for the bath's process_type
  - Managers bypass the check; expiring-soon filter in search view
  - HR Employee form: "Plating Certifications" tab

- T2.3 Material traceability chain
  - fusion.plating.batch.workorder_id (new Many2one) + production_id
    (related through WO) for full chain
  - fp.certificate gets computed batch_ids / bath_ids / batch_count
  - "Batches" stat button → list of batches used for this cert's MO,
    with their chemistry logs intact

- T2.4 Pre-treatment as first-class baths
  - process_family selection on fusion.plating.process.type
    (pre_treatment / plating / post_treatment / bake / strip / passivation /
    masking / inspection)
  - Bath search view: Pre-Treatments / Plating / Post-Treatments / Strip
    quick filters
  - Existing bath infra (logs, replenishment, SPC) now applies to pre-
    treatment baths equally

Tier 3 — Business / revenue:

- T3.1 Customer-specific price lists (fp.customer.price.list)
  - Per (customer, coating_config) with unit_price + basis (per_part /
    sqin / sqft / lb)
  - effective_from / effective_to for annual contract pricing
  - min_quantity for volume breaks (cheapest price at requested qty wins)
  - _find_price() helper resolves active entry by date + qty
  - Direct Order wizard auto-fills unit_price on (partner, coating, qty)
    change unless operator has typed an override
  - Configurator menu → Customer Price Lists

- T3.2 Quote win/loss tracking (fp.quote.configurator)
  - State values: draft → confirmed (won) / lost / expired / cancelled
  - lost_reason selection (price / lead_time / tech / spec_mismatch /
    no_bid / no_response / competitor / other) + lost_competitor_name
    + lost_details text
  - Action buttons: Mark as Lost (requires reason), Mark as Expired
  - won_date auto-set on SO creation; lost_date auto-set on mark_lost
  - New "Win / Loss" tab on configurator form

- T3.3 Actuals vs. quoted margin (mrp.production)
  - Computed monetary fields: x_fc_consumables_cost, x_fc_labour_cost,
    x_fc_actual_cost, x_fc_quoted_revenue, x_fc_margin_actual,
    x_fc_margin_pct
  - Labour = sum(WO duration × workcentre cost_hour)
  - Revenue = SO amount_untaxed via mo.origin lookup
  - New "Job Costing" group on MO form with badge-coloured margin

- T3.4 Job consumables tracking (fp.job.consumption)
  - One row per consumable event (bath replenisher, masking tape, PPE,
    chemistry): product, qty, uom, unit_cost (snapshot), total_cost,
    source, optional workorder link
  - One2many x_fc_consumption_ids on mrp.production
  - "Consumables" stat button on MO → filtered list
