feat: Transparent Portfolio Valuation & Smart Pounce Auctions

PORTFOLIO VALUATION (100% Transparent):
- Completely rewritten valuation algorithm with clear formula
- Shows exact calculation: Base × Length × TLD × Keyword × Brand
- Each factor explained with reason (e.g., '4-letter domain ×5.0')
- Real TLD registration costs integrated from database
- Confidence levels: high/medium/low based on score consistency
- Detailed breakdown: scores, factors, calculation steps
- Value-to-cost ratio for investment decisions
- Disclaimer about algorithmic limitations

SMART POUNCE - Auction Aggregator:
- New /auctions page aggregating domain auctions
- Platforms: GoDaddy, Sedo, NameJet, SnapNames, DropCatch
- Features:
  - All Auctions: Search, filter by platform/price/TLD
  - Opportunities: AI-powered undervalued domain detection
  - Ending Soon: Snipe auctions ending in < 1 hour
  - Hot Auctions: Most-bid domains
- Smart opportunity scoring: value_ratio × time_factor × bid_factor
- Affiliate links to platforms (no payment handling = no GwG issues)
- Full legal compliance for Switzerland (no escrow)

API ENDPOINTS:
- GET /auctions - Search all auctions
- GET /auctions/ending-soon - Auctions ending soon
- GET /auctions/hot - Most active auctions
- GET /auctions/opportunities - Smart recommendations (auth required)
- GET /auctions/stats - Platform statistics

UI UPDATES:
- New 'Auctions' link in navigation (desktop + mobile)
- Auction cards with bid info, time remaining, platform badges
- Opportunity analysis with profit potential
- Color-coded time urgency (red < 1h, yellow < 2h)

-    - Brandability

+    - Length_Factor: Shorter domains are exponentially more valuable
+      - 2-3 chars: ×10.0
+      - 4 chars: ×5.0
+      - 5 chars: ×3.0
+      - 6-7 chars: ×2.0

+      - Contains "ai", "crypto", etc. = up to 2.0×
+      - No premium keywords = 1.0×
+    
+    - Brand_Factor: Brandability adjustments
+      - Pronounceable: +20%
+      - All letters: +10%
+      - Contains numbers: -30%
+      - Contains hyphens: -40%
+    
+    CONFIDENCE LEVELS:
+    - High: All scores > 50, consistent factors
+    - Medium: Most scores > 40
+    - Low: Mixed or poor scores
+    
+    LIMITATIONS:
+    - Cannot assess traffic/backlinks (would need external API)

+              We aggregate domain auctions from multiple platforms (GoDaddy, Sedo, NameJet, etc.)

+              the auction platform — we don't handle any payments or domain transfers. 
+              This keeps things simple and compliant with Swiss regulations.
