CRM Dashboard

Build a lightweight CRM dashboard with the following features:

**Contacts:**
- Contacts list with columns: Name, Company, Email, Phone, Status (Lead/Qualified/Customer/Lost), Owner, Last Contact
- Add contact form: name, company, email, phone, notes, source
- Click a contact to open a detail drawer with activity timeline
- Import contacts from CSV
- Tags and custom fields

**Deals Pipeline:**
- Kanban board with columns: Lead, Qualified, Proposal, Negotiation, Won, Lost
- Each card shows: deal name, contact name, value, expected close date
- Drag-and-drop cards between columns
- Clicking a card opens a drawer with full deal details, activity log, and notes

**Activity:**
- Log activities on a contact or deal: Call, Email, Meeting, Note — each with a timestamp and free-text body
- Activity timeline per contact and per deal, sorted newest first
- Weekly digest on the dashboard: "You logged 12 activities this week, closed 2 deals worth £8,400"

**Dashboard Overview:**
- KPI cards: Open deals, Pipeline value, Deals won this month, Deals lost this month
- Recent activity feed
- "Stale deals" alert: deals with no activity in 14+ days

**Design:**
- Clean, two-pane layout: sidebar nav + main content
- Drag-and-drop feels smooth (use @dnd-kit or similar)
- Responsive, but optimise for desktop — reps don't use CRMs on their phones
- Dark mode toggle

Store everything in Supabase. Each user sees only their own contacts and deals (RLS). Support team sharing via a simple 'team_id' column.
