Note

Low Risk
Primarily version/changelog updates and dependency bumps; no runtime logic changes in this diff beyond consuming the new @metamask/account-tree-controller version.

Overview
Bumps the monorepo release version to 915.0.0 and publishes @metamask/account-tree-controller 7.1.0 (with updated changelog entries/links).

Updates dependent packages (@metamask/assets-controller, @metamask/assets-controllers, @metamask/earn-controller, and @metamask/perps-controller) to require @metamask/account-tree-controller@^7.1.0, and refreshes yarn.lock accordingly.
