Implement BQL-based balance query methods
Added get_user_balance_bql() and get_all_user_balances_bql() methods that use Beancount Query Language for efficient balance queries. Benefits: - Replaces 115-line manual aggregation with ~100 lines of BQL queries - Server-side filtering and aggregation - Expected 5-10x performance improvement - Handles multi-currency positions (SATS, EUR, USD, GBP) - Returns same data structure as manual methods for compatibility Implementation: - get_user_balance_bql(): Query single user's Payable/Receivable accounts - get_all_user_balances_bql(): Query all users in one efficient query - Position parsing handles both dict and string formats - Excludes pending transactions (flag != '!') Next steps: 1. Test BQL queries against real Castle data 2. Compare results with manual aggregation methods 3. Update call sites to use BQL methods 4. Remove manual aggregation methods after validation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
