fix(ic-icrc1-test-utils): handle AuthorizedMint and AuthorizedBurn in match arms

Non-exhaustive pattern errors after adding the two new Operation variants.
- effective_fee match: return None (no fee for authorized supply changes)
- balance tracking: mirror Mint/Burn credit/debit behaviour
- update_valid_allowance_from: check affected account validity
