feat(jobs): Phase 3 light refactors — parallel job/step links on dependent models

Adds x_fc_job_id / x_fc_step_id Many2ones via _inherit on:
- fusion.plating.batch (workorder_id stays for legacy MRP-bound batches)
- fusion.plating.quality.hold
- fp.certificate
- fp.thickness.reading
- fusion.plating.delivery (parallel to existing job_ref Char)
- fp.racking.inspection (parallel to existing production_id)

fp.job.action_confirm now also calls a best-effort racking-inspection
auto-create. The current fp.racking.inspection still has a required
production_id, so the helper skips cleanly when this job has no MO link
(pure-native mode). Phase 9 cutover flips the required FK to fp.job.

Strategy: parallel coexistence — bridge_mrp's existing fields stay
populated; this adds NEW fields populated by the native flow. Phase 9
cutover stops populating the old fields.

Adds fusion_plating_batch + fusion_plating_receiving to jobs module
depends.

Note: spec referenced fp.batch / fp.quality.hold; the actual models
in this codebase are fusion.plating.batch / fusion.plating.quality.hold
— used the real model names.

Manifest 19.0.1.5.0 → 19.0.1.6.0. 29 jobs tests pass.

Part of: native job model migration (spec 2026-04-25)
