[Enhancement]: Enable IFRAME activation

[miltuss]

Type of Enhancement

None

Describe the Feature/Enhancement

Since update 2.17.3, IFRAME integration no longer works with ABS. And some Reverse-proxy like Caddy cannot activate ABS IFRAME. An ENV variable could give users the choice of whether or not to activate the IFRAME.

Why would this be helpful?

I use ABS with the Organizr application which integrates other applications in IFRAME

Since this is a common request I made this a server setting.

Allowing iframe embed can also be enabled via an env variable ALLOW_IFRAME with a value of 1.

Note: If it is enabled through the env variable there will be an error message shown when attempting to disable it in server settings. Env variable takes precedence.

Fixed in v2.17.5.
