This commit fixes two critical balance update issues in the Android app:
1. Added balanceChanged.emit() on blockchain_updated event
- Fixes coinbase outputs not showing when they mature (120 blocks)
- Ensures balance updates when new blocks arrive
- Resolves issue where only partial mining rewards were displayed
2. Fixed typo: satInt → satsInt in BalanceDetails.qml
- Lightning swap button now works correctly
Related to previous fix on tx_height_changed event handler.
