Note

Medium Risk
Mostly mechanical version bumps, but it rolls out a new @metamask/messenger minor version across many packages, so any behavioral/type changes in the messenger could have wide impact.

Overview
Updates the monorepo version to 945.0.0 and releases @metamask/messenger@1.2.0 (including changelog updates).

Propagates the @metamask/messenger dependency bump from ^1.1.1 to ^1.2.0 across many controller/service packages and records the change in their CHANGELOG.md entries.
