feat: Expose TransactionController:wipeTransactions through messenger

[GuillaumeRx]

Explanation

This adds TransactionController:wipeTransactions to MESSENGER_EXPOSED_METHODS and exports the type, as this was missed in #8183.

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 only adds a new messenger-exposed method and corresponding TypeScript action type/export, without changing transaction processing logic.

Overview
Adds messenger support for TransactionController:wipeTransactions by including it in MESSENGER_EXPOSED_METHODS and introducing the corresponding TransactionControllerWipeTransactionsAction in the generated method action types.

Updates the package public API exports and documents the new exposed action in the transaction-controller changelog.
