fix: comprehensive PostgreSQL Decimal handling across all endpoints
Fixed all remaining Decimal → float conversion issues found by audit.

**Fixed Endpoints:**
1. Weight Stats: min/max/avg calculations
2. Activity Stats: kcal/duration accumulation
3. Nutrition Weekly: average calculations
4. Template Variables: all f-string Decimal formatting
5. CSV Export: all numeric value formatting
6. JSON Export: added Decimal handler
7. ZIP Export: added Decimal handler
8. Correlations: weight, nutrition, caliper values

**Changes:**
- Added `from decimal import Decimal` import
- Weight stats: convert to float for min/max/avg
- Activity: float() in sum() and accumulation
- Nutrition: float() in averages
- Template vars: float() for weight_aktuell, kf_aktuell, goals
- CSV: float() in all f-strings (weight, circ, caliper, nutrition, activity)
- JSON/ZIP: custom decimal_handler for json.dumps()
- Correlations: float() for all numeric DB values

Prevents:
- TypeError in math operations
- "Decimal('X')" strings in exports
- JSON serialization failures

All numeric values from PostgreSQL now properly converted to float.
