Before this change, the custom account integration test padded the recording-mode simulation with fixed factors: four times the instructions, three times the disk read bytes and a fixed fee. It also built the footprint by hand, because that simulation does not run the account contract's __check_auth. On testnet under Protocol 30 the padded budget was too small: add_limit failed with resource_limit_exceeded inside __check_auth, 2,084,115 instructions consumed against 1,616,672 declared.

This change:

• Signs the auth entries, re-simulates the transaction in enforcing auth mode and takes that footprint, resources, and fee, for add_limit and for transfer.
• Asserts the rejection of the over-limit transfer with one signer on the enforcing simulation's result error (Error(Auth, InvalidAction) with the contract's error 3) and no longer submits it.
• Removes the padding, the hand-built footprint keys and two unused imports.

Verified on testnet: the class passed three times on this tree, the enforcing simulation of add_limit at 2,283,077 instructions. Unit suite and static analysis green.
