Setup: the occ command differs for Codespaces (audit the whole path)

The "Common commands" section gives a single universal occ command that only works for local docker-dev:

./scripts/occ.sh nextcloud --

Codespaces users need:

docker exec master-nextcloud-1 sudo -u www-data php occ

So anyone following the Codespaces path hits a failing command in a section presented as universal.

Scope

Split the occ guidance by environment in content/shared/setup.md. The module already has per-OS paths (macOS / Ubuntu / Windows / Codespaces), so the structure to hang it on exists.

Worth auditing the whole Codespaces path while in there — this was flagged as a "Codespaces path audit" and this command is the known instance, not necessarily the only one.

Done when

Each environment shows the occ invocation that actually works for it, and the Codespaces path has been walked end to end.

Read content/shared/setup.md and compare the existing macOS, Ubuntu, Windows, and Codespaces paths, starting with the Common commands section and its occ invocations. Walk the Codespaces path end to end, then update each environment's occ guidance and verify that the documented commands work for their intended path.
