"""Tests for consistent error handling in wallet CLI (bounty #16253).

Covers every failure path in cmd_balance, cmd_export, cmd_send, cmd_history,
and the main() catch-all to ensure:
- Clear distinct error messages on stderr
- Non-zero exit codes per the documented scheme
- No silent wrong-value returns
