Phase 3 closed — the store and broker are ordinary modules, issue 051 fixed

Marks WBS 3.2/3.3/3.4 done and resolves issue 051: the foundation's store and
broker are adopted in place as the postgres and lavinmq modules, upgradeable
through their stated windows, source-tracked by status. A bare-metal mesh runs
one postgres and one lavinmq, proven 22/22 in the one-node lab. The two follow-up
gaps are tracked as issues 054 and 055.

 **Done when.** A mesh built from bare metal runs one postgres and one lavinmq, and can upgrade
 either — so the twelve-module floor has no specialty left in it.

+The foundation's store and broker are adopted in place as the ordinary `postgres` and `lavinmq`
+modules (WBS Phase 3). Each module declares the container the foundation raised — the same name,
+image, ports, volumes and args — so the applier reconciles it rather than raising a second server;
+`mesh-host`'s `InstallStore` (phase3.go) carries in the genesis credentials the mesh cannot invent.
