Initial multi-tenant blog host

Go + Postgres application serving a management dashboard on the base
domain and one public blog per subdomain. Markdown posts organised in
pages, form-based theme customisation, image uploads stored in Postgres,
JWT cookie sessions with CSRF, superadmin user management, RSS feeds.
Docker/compose deployment and a Makefile-driven dev environment with
seed data.
