ui(rename): "Plating Job" -> "Work Order" / display "WO # 01368"

Standardise user-facing terminology across 5 modules (27 files):
  - display_name compute: 'Work Order # 01368' -> 'WO # 01368'
  - _description on 5 models: Plating Job{," Step"," Step Time Log"," Margin Report"," Recipe Node Override"} -> Work Order equivalents
  - field labels (string=...) on 13 Many2one / One2many fields
    across fp.batch, fp.thickness_reading, fp.quality.hold,
    fp.job_consumption, fp.portal.job, fp.certificate, fp.delivery,
    fp.quality.check, fp.racking.inspection, res.partner, sale.order
  - XML view labels: action names, list/form/search strings,
    portal template names, dashboard tile titles

What's deliberately preserved:
  - DB model name 'fp.job' (technical identifier — used by
    sale_order.x_fc_plating_job_ids and all comodel refs)
  - Module name 'fusion_plating_jobs' (directory / import path)
  - Settings -> Apps display label 'Fusion Plating Jobs' (module
    identity for Odoo's app picker)
  - 'Use Native Plating Jobs' migration toggle (internal mechanism
    flag, not user-facing terminology)

Verified on entech: WH/JOB/01368 now displays as 'WO # 01368'
everywhere humans look (form header, breadcrumbs, M2O dropdowns,
error messages, smart-button titles).
