jschoubben d301e05794 fix: postgres consumers connect to the db the mesh named (the login), not a hardcoded app name
The postgres provisioner creates each consumer a database named after the login the mesh
minted (mesh_<node>_<module>), per ADR 0048 -- 'a same-named database under exactly that
login'. But baserow, letta, umami, gitea, keycloak and nextcloud each hardcoded their app db
name (DATABASE_NAME=baserow, /letta, /umami, NAME=gitea, /keycloak, POSTGRES_DB=nextcloud),
so the service connected to a database that does not exist ('database letta does not exist').
Each now uses ${bound:postgres-database:as} as the db name -- the login, which is also the db
name -- matching the working meshboard pattern and the provisioner's actual behaviour.

Found by the two-node DB-consumer lab install (mesh-lab assigned-two-node-db); baserow is
proven connecting and running there. The S3 bucket name is the same class of assumption and is
a separate follow-up (s3 identity has its own length bound).
