fix: consistent error handling + exit codes in wallet balance check CLI [fj4WqyCCw3C5ShR1RfB7MoBPTpkRrBFYP1uT35g3MvT]
Fixes two inconsistencies in tools/rustchain_wallet_cli.py (bounty #16253): 1. cmd_export: add explicit FileNotFoundError handling so missing wallet returns EXIT_WALLET_NOT_FOUND (4) instead of the generic EXIT_UNKNOWN_ERROR (6) from main()'s catch-all. 2. main(): Change lowercase 'Error: {e}' to uppercase 'ERROR: {e}' to match the consistent uppercase style used by every other error path in the CLI (cmd_balance, cmd_send, cmd_history, etc.). 3. Add 15 tests covering every failure path in cmd_balance, cmd_export, cmd_send, cmd_history, _safe_json, and _safe_json_object — network errors, 404, 500, malformed JSON, missing fields, missing wallet. Closes #7889 Closes Scottcjn/rustchain-bounties#16253
