fix: Check HTTPS_ENABLED env var before HTTPS redirection

[Rohanlogs]

Description

• Uses HTTPS_ENABLED environment var for HTTPS redirection

• Adds world config loader for docker

• Users can now configure worlds directly from server repo, when running prod build

• Environment variable is now passed to all 23 routes which use the header.ejs:

Why

For production build to work, these changes need to be made in the Website repository, as docker is pulling it from Server, see #1074

I added an extra file https://github.com/2004Scape/Website/pull/7/files#diff-51f6929abdfb9361c8f1466cd14634dbb7f67c2a8eb5de79aa8ff9e61c46df5a

This doesn't change anything with how worlds work, its only to make docker production build easier (I'll add clear instructions for this in #1074)

Looks good. Note: world config will be moved to the database in one of the next feature updates so this may need to be touched on again then.
