feat(transaction-controller): include RedeemerEnforcer in 7702 gas fee token simulation

[matthewwalsh0]

Explanation

Clients are adding a RedeemerEnforcer caveat to the delegations they sign for the gasless EIP-7702 relay flow, so only the relay signers can submit the redeemDelegations call. Sentinel builds its own delegation when estimating 7702 gas fee tokens, so without the caveat the estimate falls slightly short.

• getGasFeeTokens now sets suggestFees.withRedeemerEnforcer to match with7702, so the estimate includes the enforcer's gas.
• The flag only affects the 7702 delegation estimate. Balance change simulations and non-7702 fee rows are unchanged, and Sentinel ignores it on chains with no relay signers configured.
