feat: rich Pipeline board — unified Lead/Deal/WO Kanban with SLA + drag-drop transitions

Replaces the bare 6-status WO Kanban with the unified Pipeline view from
/tmp/service/todo/psauto-pipeline-redesign.html. Six columns now span the
entire customer journey end-to-end:

  Cerere nouă → Calculație → Programat → În lucru → Gata → Achitat azi
  └─ Lead/Deal  └─ Deal      └─ Deal     └─ WO       └─ WO    └─ WO+Payment

Cross-model drag-drop transitions:
- Lead → Calculație: Lead::convert() creates Deal at stage=contact, marks
  quote_sent_at = now, quote_status = sent
- Deal (any earlier stage) → În lucru: spawns a WorkOrder from the deal
  (client, vehicle, master, total, complaint), sets deal.stage=in_work,
  links wo.deal_id
- WO → Gata: status=ready + fires NotificationDispatcher::workOrderReady
  so client gets Telegram/email automatically
- WO → Achitat: creates Payment for remaining balance + status=done,
  closed_at=today (pay_status syncs to paid via Payment booted hook)

Rich card content per the mockup:
- Red urgent stripe (left border) for Deal.urgent or WO.urgency!=normal
- Source tag (Instagram/Site/Apel/etc.) on lead/deal cards
- Quote status badge ("Trimis · fără răspuns" amber / "Văzut ✓" blue /
  "A răspuns" green) based on deal.quote_status
- Scheduled time + bay tag ("05.06 · 09:00" + "Post 2")
- Fișă FL-NNN purple tag on WO cards
- "Necesită aprobare" amber tag when wo.status=agreement
- Progress bar (purple, 0-100%) on in-work cards: works_done + parts_installed
  over total lines
- SLA time line per card with overdue red color:
  * Lead 60+ min not contacted = overdue
  * Quote 2h+ no response = overdue
  * Ready 30+ min not paid = overdue (with phone icon)
  * WO past ETA = overdue
- Assignee avatar (deterministic CRC32 color: blue/green/purple/amber)
- Amount in MDL, formatted

Stat strip (6 metrics computed live):
- Total deals active (sum of cols 1-5)
- MDL pipeline total
- MDL closed today (Payment sum where paid_at=today)
- Necesită acțiune (overdue + urgent + pending approval)
- Rata conversie 30d (won / (won+lost) %)
- Depășit termen (count WO past eta_at)

Filter chips wire-driven: Toate / Ale mele (assigned_to=me) /
Urgente (urgent=true OR wo.urgency!=normal) / Azi.

View toggle: Kanban ↔ Listă (table with all cards flat, sortable by stage).

Slide-in detail panel:
- 6-step stage stepper highlighting current
- Client / Telefon (blue clickable) / Auto / Sursă / Responsabil / Sumă /
  De achitat (live computed balanceDue for WOs)
- Note / Reclamație
- Linked Fișă card with status badge, progress, ETA, "necesită aprobare"
  alert + tracking link
- Activity timeline from Spatie activity-log
- Quick actions: WhatsApp (wa.me/<phone>), Sună (tel:), SMS (sms:),
  Deschide (jumps to Filament resource edit)

DealResource hidden from nav (shouldRegisterNavigation=false) since
PipelineBoard is the canonical entry, but its edit/create routes stay
intact — the panel deep-links to them.

Auto-refresh: wire:poll.10s keeps the board live without WebSocket
dependency. Drag-drop is HTML5 native + Livewire wire:click for ops.

Dark mode supported via CSS variables overridden in .dark scope.

Migration: extend deals table with urgent, quote_sent_at, quote_status,
quote_seen_at, scheduled_at, bay, confirmed_at, confirmed_via,
last_action_at. Idempotent (hasColumn guards). Deal model auto-updates
last_action_at on saving.

Tests: 7 new + full suite 180/180 green (was 173).
- partition leads/deals/wos by column
- stats computation: active, pipeline_mdl, closed_today_mdl
- lead→quote transition converts lead into deal
- deal→in_work creates WorkOrder linked back to deal
- wo→paid creates payment for balance + marks done
- filter "mine" narrows to assigned user
- openCard loads panel detail with correct stepper position
