This pull request addresses a regression in how lookup table accounts are handled in vault transaction execution, ensuring correct alignment with on-chain validation. The main change is to build the lookup table account metas from the message's referenced tables in the correct order, rather than from the raw caller-supplied slice. This prevents execution failures when the supplied lookup tables are a superset or reordered. Additionally, comprehensive regression tests have been added to verify this behavior and error handling for missing referenced tables.

Fixes to lookup table account meta handling:

• The VaultTransactionMessageExt trait's implementation now constructs lookup_table_account_metas from message.address_table_lookups in message order, ensuring only referenced tables are included and in the correct order. This matches the on-chain validator's expectations and prevents desyncs that could brick execution.

Regression tests for correct ALT handling:

• Added a new test file vault_transaction_execute_alt.rs with regression tests to verify that:
  • Only message-referenced lookup tables are emitted, in message order, regardless of the caller-supplied slice's order or superset.
  • The helper returns an error if a referenced lookup table is missing from the supplied accounts.
