Convert baserow, letta, invoicing to mesh catalog DB consumers

Mirror the postgres-consumer shape (keycloak/nextcloud): requires the
backing service(s), binds/secrets for the delivered credential, and a
server container that reads it from an interpolated env file.

- baserow: consumes postgres-database + redis-cache; tooled (dormant
  until an account is configured, like gitea's token).
- letta: consumes postgres-database; tooled, live via a mesh-minted
  server-password injected into both server and runtime.
- invoicing: consumes mongodb-database + s3-bucket; plain two-container
  service (app + api), no tools.

Digests pinned for baserow and letta; invoicing keeps private-registry
tags (DIGEST-UNRESOLVED). redis-cache and mongodb-database consumer
shapes are inferred (no prior consumer in the catalog).
