PR Summary

Low Risk
Test and versioned-constants snapshot updates for fee/resource accounting; no production execution-path logic changes beyond refreshed constant numbers.

Overview
Extends test_execute_txs_inner_resources so declare transactions are measured alongside invoke: the test now runs two txs, subtracts blockifier business-logic resources from full OS trace resources per tx, and writes the declare remainder into versioned constants as a constant execute_txs_inner.Declare entry (invoke overhead is still updated the same way).

blockifier_versioned_constants_0_14_4.json is refreshed with the new declare OS scaffolding cost (3938 steps, 92 range-check builtins, up from the previous placeholder values).

The declare path uses a stable, unmodified class (DATA_GAS_ACCOUNT_CONTRACT_*) so measurements do not drift from recompilation. DeployableForResourceMeasurement gains __validate_declare__ and matching Sierra/CASM artifacts so account validation for declare is realistic for resource tests. Minor formatting-only edits appear in os_resources_test_contract.cairo.
