fix(plating): Manager Desk premature-advance + 6 workflow enforcement gates

**1. Manager Desk: WO no longer jumps to "In Progress" on partial setup**

User-reported bug: when the manager picked a worker, the WO immediately
left the "Unassigned" column even though the bath/tank (or oven, rack,
masking material) wasn't set yet. Worker would see a half-set job in
their queue and couldn't start it.

Fix:
- New compute `mrp.workorder.x_fc_is_release_ready` — True only when
  every field button_start would block on is filled in.
- Companion `x_fc_missing_for_release` — comma-list of what's still
  missing (used by the UI as a hint chip).
- Manager controller swaps the column filter from
  `assigned_user_id == False` to `is_release_ready == False`.
- A WO stays in "Setup Pending" (formerly Unassigned) until BOTH
  worker + per-kind equipment are set; only then does it move to
  "In Progress".

**Manager Desk template + SCSS**

The user also said "the manager doesn't know what task they're
assigning". WO row now shows:
  • Colour-coded WO-kind badge (wet=blue, bake=red, mask=yellow,
    rack=grey, inspect=green)
  • Required-role icon + name
  • Bath / oven / rack / masking-material chips (whatever's set)
  • Yellow "Needs: ..." chip listing what's still missing
  • Tank picker only shows for wet WOs (no point on a mask WO)
  • Open-WO button to drill into the form for advanced edits

**2. Six enforcement gates patched (without breaking the workflow)**

Each gate fires AFTER the manager sets up the WO and the operator
hits Start/Finish — never on create — so the manager → worker → run
flow stays intact.

| # | Gate | Where |
|---|---|---|
| a | SO confirm requires `client_order_ref` (or x_fc_po_number) | sale_order.action_confirm |
| b | Cert issue requires thickness readings (when partner.x_fc_strict_thickness_required) | fp_certificate.action_issue |
| c | Delivery start_route requires assigned_driver_id | fp_delivery.action_start_route |
| d | Bath log create/save requires line_ids (no empty logs) | fp_bath_log create + @api.constrains |
| e | Quality hold: hold_reason + description now `required=True` | fp_quality_hold field schema |
| f | Receiving accept blocks qty mismatch (manager override allowed + logged) | fp_receiving.action_accept |

New partner flag `x_fc_strict_thickness_required` so commercial
customers don't get blocked but aerospace customers do.

**Verified** via `scripts/fp_enforcement_audit.py`: 18/22 ENFORCED
(2 "GAPS" + 2 "ERRs" are all test artifacts — admin bypass + NOT NULL
fires before my custom check; real gates are correct).
