docs(fusion_plating): document tablet redesign architecture in CLAUDE.md (P5.1)

Replaces the stale "Plant Overview Dashboard" section with a current
"Shop Floor Architecture" section covering the Phase 1-4 deliverables:

  - 3 OWL client actions (Landing / JobWorkspace / Manager Dashboard)
  - 5 shared OWL services
  - Backend endpoints (workspace / landing / manager)
  - Auto-pause cron config knob (ir.config_parameter name)
  - Key new model fields with their purpose
  - Operator ACL lift summary
  - Deprecated-but-still-live legacy surfaces (Phase 5 cleanup pending)
  - Old patterns to avoid

Links to the spec + plan docs as the authoritative reference.

+## Shop Floor Architecture (2026-05-22 tablet redesign — Phases 1-4)
+
+Spec: [docs/superpowers/specs/2026-05-22-shopfloor-tablet-redesign-design.md](docs/superpowers/specs/2026-05-22-shopfloor-tablet-redesign-design.md)
+Plan: [docs/superpowers/plans/2026-05-22-shopfloor-tablet-redesign-plan.md](docs/superpowers/plans/2026-05-22-shopfloor-tablet-redesign-plan.md)
+
+**Three OWL client actions** (registered under `registry.category("actions")`):
+- `fp_shopfloor_landing` — Workstation kanban entry. Station-scoped or All-Plant mode toggle. Tap a card → JobWorkspace. Replaces the legacy `fp_shopfloor_tablet` and folds in `fp_plant_overview`.
+- `fp_job_workspace` — Full-screen single-WO surface. Sticky header (WO #, customer, qty, workflow chip), sticky 9-stage workflow bar, step list with GateViz blockers, side panel (spec/attachments/chatter), sticky action rail (Hold/Note/Milestone). Opens from kanban tap, smart button, QR scan, or manager card tap.
+- `fp_manager_dashboard` — Manager Desk with 4 sibling tabs: **Workflow Funnel** (default), **Approval Inbox**, **Plant Board** (existing 3-column), **At-Risk** (trending late + hold reasons + bottleneck heatmap).
+
+**Five shared OWL services** in `fusion_plating_shopfloor/static/src/js/components/`:
+- `WorkflowChip` — workflow.state pill + optional next-action hint
+- `GateViz` — "Can't start because…" explainer (reads `fp.job.step.blocker_kind`/`reason`)
+- `FpSignaturePad` — Dialog canvas signature capture
+- `FpHoldComposer` — Dialog hold-create form with reason picker + qty + photo
+- `FpKanbanCard` — standard WO/step card with embedded WorkflowChip + blocker badge
+
+**Backend endpoints (Phase 1-4):**
+- Workspace: `/fp/workspace/{load,hold,sign_off,advance_milestone}`
+- Landing: `/fp/landing/kanban` (mode=station|all_plant)
+- Manager: `/fp/manager/{overview,funnel,approval_inbox,at_risk}`
+
+**Auto-pause cron — fixes 411-hour ghost timers:**
+- `_cron_autopause_stale_steps()` runs every 30 min
+- Threshold from `ir.config_parameter` **`fp.shopfloor.autopause_threshold_hours`** (default 8.0)
+- Recipe nodes opt out via `fusion.plating.process.node.long_running=True` for 24h bakes etc.
+- Flips `state=in_progress` idle > threshold to `paused` with chatter audit
+
+**Key model fields added (Phase 1-4):**
+- `fp.job.display_wo_name` — "WO # 00001" formatter for tablet/dashboard (model `name` field stays `WH/JOB/…`; system-wide sequence rename deferred)
+- `fp.job.late_risk_ratio` — stored Float (remaining_planned / minutes_to_deadline) driving At-Risk view
+- `fp.job.active_step_id` — computed M2o to currently in_progress step
+- `fp.job.step.blocker_kind` / `blocker_reason` / `blocker_jump_target_*` — drives GateViz
+- `fp.work.centre.bottleneck_score` / `avg_wait_minutes` — drives At-Risk bottleneck heatmap
+
+**Operator ACL lift (per "techs wear multiple hats" rule):**
+- `fp.certificate` — operator gained write (flip draft → issued from tablet)
+- `fp.thickness.reading` — operator gained create+write (Fischerscope capture from tablet)
+- `fp.job.node.override` — operator gained read (see opt-out badges on steps)
+- Supervisor-only ops (step Skip, hold Release) enforced in `workspace_controller.py`, not ACL
+
+**Deprecated but still live** (cleanup is Phase 5):
+- OWL components: `fp_shopfloor_tablet`, `fp_plant_overview` — registered but no menu points at them
+- Endpoints: `/fp/shopfloor/tablet_overview`, `plant_overview`, `queue` — marked DEPRECATED with INFO log lines, bodies intact for back-compat
+- `/fp/shopfloor/plant_overview/move_card` is **NOT** deprecated — the new Landing component uses it for drag-and-drop
+
+**Old patterns to avoid:**
+- Don't read `fp.job.name` for display — use `display_wo_name` everywhere on tablet/dashboard
+- Don't add SCSS that uses raw hex without an `@if $o-webclient-color-scheme == dark` branch (dark mode breaks otherwise; see existing `_workflow_chip.scss` as the template)
+- Don't add `web.assets_web_dark` entries to the manifest — Odoo 19 auto-compiles `web.assets_backend` SCSS into both bundles
+- Don't bypass `_fp_should_block_predecessors()` when computing step blockers — keep `blocker_kind=predecessor` logic in sync with `can_start`
