Codemod db pass-through calls: messages + runs + approvals + company (C1 part 2/3)

Rewrite ~376 call sites for messages, runs, approvalsMod, and company
domains and delete the corresponding pass-through methods on
AppDatabase / AppDatabaseBase. Structural type references
(ReturnType<HandlerDeps["db"]["getRun"]>) and SweepStaleReviewsDeps-style
mocks are updated to route through the owning sub-module.
