feat(deploy): build docmost from acadedoc fork instead of upstream image

- compose.yml : replace 'image: docmost/docmost:latest' with build context
  pointing to ./docmost (the AcadeDoc fork repo cloned separately)
- Image tagged 'acadenice/acadedoc:local' for visibility in docker images
- README : document the two-clone setup (formation-hub + AcadeDoc fork)
  required to run the stack with all Acadenice extensions

Without this change, prod runs vanilla Docmost without any of the 30+
AcadeDoc commits (api-keys, audit-log, OIDC, sync blocks, templates,
comments threads, mentions, graph view, timeline, branding, Brevo SMTP).

Fork remote: https://git.acadenice.com/AcadeNice/AcadeDoc.git
Branch: acadenice/main
