refactor: Simplify Portfolio page - remove unreliable data

SIMPLIFIED STATS:
- Removed: Total Invested, Est. Value, Profit/Loss
- Added: Expiring Soon (domains expiring in 30 days)
- Added: Need Attention (domains with health issues)
- Kept: Total Domains, Listed for Sale

SIMPLIFIED TABLE:
- Domain column: name + registrar
- Added column: simple date added
- Expires column: with color-coded expiry warnings (30d, expired)
- Health column: quick health status
- Actions: Three-dot dropdown menu

THREE-DOT MENU:
├── Health Check
├── Edit Details
├── ─────────────
├── List for Sale (accent color)
├── Visit Website
├── ─────────────
├── Record Sale
└── Remove (danger)

SIMPLIFIED SUBTITLE:
- Shows domain count + expiring soon count
- No more profit/loss display

This focuses on reliable, actionable data:
✅ Domain names (100% accurate)
✅ Expiry dates (user input)
✅ Health status (real-time check)
❌ Valuations (unreliable estimates)
❌ Profit/Loss (depends on estimates)
