feat(jobs): add fp.work.centre native model

Replaces mrp.workcenter for plating. Domain-specific kinds
(wet_line/bake/mask/rack/inspect/other) drive release-ready
validation on steps. ACLs follow existing supervisor/manager
hierarchy.

Note: spec listed default_oven_id Many2one to fusion.plating.oven
but that model does not exist in core (the bake-oven model
fusion.plating.bake.oven lives in fusion_plating_shopfloor, which
core cannot depend on). Field omitted; the bridge that adds
fp.job/fp.job.step can re-introduce it via _inherit later.

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