feat(plating-landing): role-based dispatch resolver + picklist expansion

Phase E of permissions overhaul. The landing resolver now dispatches
based on the user's highest role (per spec Section 3):

  Owner          -> Manager Desk
  Quality Mgr    -> Quality Dashboard
  Manager        -> Manager Desk
  Sales Manager  -> Sale Orders
  Shop Manager   -> Plant Kanban (v2 layout) or Workstation (legacy)
  Sales Rep      -> Quotations
  Technician     -> Plant Kanban / Workstation

User override (x_fc_plating_landing_action_id) still wins; company
default and hardcoded Sale Orders are fallbacks. Layout-flag-aware via
ir.config_parameter['fusion_plating_shopfloor.layout'] (v2 vs legacy).

x_fc_pickable_landing field added to BOTH ir.actions.act_window AND
ir.actions.client (Manager Desk / Plant Kanban / Quality Dashboard
are client actions). Resolver helper polymorphically calls
_render_resolved() on either model.

Tagged 3 of 4 new actions pickable: Manager Desk, Plant Kanban,
Quality Dashboard. (action_fp_shopfloor_landing doesn't exist as an
XML record — it's a JS component name only; legacy layout falls
through to company default gracefully via raise_if_not_found=False.)

Tightened picklist domain to filter by user accessibility (Technician
no longer sees Manager Desk in the dropdown). New compute field
res.users.accessible_landing_action_ids runs check_access_rights on
each pickable action.

Tests in fusion_plating/tests/test_landing_resolver.py.

CLAUDE.md updated with two durable rules:
  - x_fc_pickable_landing lives on BOTH act_window and actions.client
  - Role-based dispatch precedence and helper API
