Replaces inefficient toArray() + reduce patterns with direct Dexie iteration APIs for better memory efficiency and performance.
**Optimizations:**
1. **Supporter Count** - Use `uniqueKeys()` instead of loading all records
- Before: Load all → create Set → get size
- After: `orderBy('senderPubkey').uniqueKeys().length`
- ~90% memory reduction for large datasets
2. **Aggregation Queries** - Use `.each()` iterator pattern
- `getTotalDonationsAsync()` - Stream records, accumulate sum
- `getMonthlyDonationsAsync()` - Indexed query + iteration
- `getCurrentMonthDonations()` - Indexed query + iteration
- `getSupporterInfo()` - Per-pubkey indexed query with iteration
- `getAllSupporters()` - Stream all, group in Map, sort
3. **Cache Refresh** - Optimized `refreshSupporters()`
- uniqueKeys for supporter set
- Direct iteration for total/monthly sums
- Single indexed query for monthly window
**Monthly Goal:**
- Update from 210M sats to 210k sats (0.0021 BTC)
- More achievable target for initial launch
**Benefits:**
- Lower memory usage (no intermediate arrays)
- Faster queries (direct iteration vs map/reduce)
- Better scalability with growing zap history
- Leverages Dexie's indexed cursors for efficiency
