Function process_authorizations 

pub fn process_authorizations<T: Config>(
    authorization_list: &[AuthorizationListEntry],
    origin: &T::AccountId,
    exec_config: &ExecConfig<T>,
) -> AuthorizationResult<BalanceOf<T>>

Process a list of EIP-7702 authorization tuples.

For new accounts the ED is drawn from the transaction fee via FeeInfo::withdraw_txfee and resolved into the account; the delegation deposit itself is charged via Pallet::charge_deposit. The pre-dispatch weight reservation comes from worst_case_authorization_weight; the returned weight_refund is the gap between that baseline and the actual cost incurred.

Note: We process authorizations OUTSIDE the transaction context so delegation changes persist even if the call fails.

Returns the aggregated AuthorizationResult directly — every per-auth failure (spec validation step or post-validation rollback) is handled by continue inside the loop, so this function is structurally infallible from the caller’s perspective.
