Fix consolidation settings not saving

- Updated API endpoint to handle simple key-value format from frontend
- Endpoint now accepts both old format (consolidation_settings array) and new format (btc/eth/usdt/usdc keys)
- Maps lowercase keys to uppercase crypto_type in database (btc -> BTC, etc)
- Only updates threshold_amount, preserves admin_address and is_enabled
- Fixes issue where changing page would reset values to defaults
