Checklist

• I've updated the test suite for new or updated code as appropriate
• I've updated documentation (JSDoc, Markdown, etc.) for new or updated code as appropriate
• I've communicated my changes to consumers by updating changelogs for packages I've changed
• I've introduced breaking changes in this PR and have prepared draft pull requests for clients and consumer packages to resolve them

Note

Low Risk
Low risk: this PR only expands the TransactionController messenger/public API surface (types + exposed method list) without changing transaction processing logic, but it may require downstream consumers to update allowed actions/imports.

Overview
Exposes additional TransactionController methods via the messenger by adding new messenger action type definitions and including these methods in MESSENGER_EXPOSED_METHODS.

Adds/exports actions for updateSecurityAlertResponse, updateTransactionGasFees, updatePreviousGasParams, updateSelectedGasFeeToken, and updateRequiredTransactionIds, and documents the new messenger actions in the transaction-controller CHANGELOG.md.
