The Create Workspace button in the top-header dropdown was still calling
`window.alert("Create workspace (placeholder)")` instead of opening the
real CreateWorkspaceDialog. Wires it to the same dialog the sidebar
workspace switcher uses.
Also clarifies in .env.example and AGENTS.md that the canonical Postgres
database name is `echodo` everywhere (local, Coolify, drizzle ledger,
docker-compose POSTGRES_DB). A stale `tasks` database on CT 102 from the
pre-rename era was the root cause of the 2026-06 Authentik "Configuration"
SSO outage: Coolify correctly pointed at `echodo` (which was empty), while
the only initialized schema lived in the relic `tasks` DB.
