Docs: fix self hosting local deploy protocol (#433)

Browse source 
* fix: skip Docker check in ensure-postgres.sh when remote DATABASE_URL is set

When DATABASE_URL points to a non-localhost host, the script now skips
all Docker operations and only verifies remote DB connectivity via
pg_isready directly.

* fix: honor DATABASE_URL for remote postgres preflight

* fix(make): clarify stop output for remote database

* docs: add local deployment protocol guidance to SELF_HOSTING.md

Clarify that local deployments without TLS should use http:// and ws://
instead of https:// and wss://.
