mark nullable types explicitly

PHP 8.4 will throw a warning where type hints without a ?prefix are used
and nullable parameters can be passed.

I'm not sure if I found all occurances, but we still rarely use type

Remove the htmlok and phpok embedding options

Both options have grave security implications and novice users seem to
ignore advice about them. In the last decades I never came across a wiki
that had legitimate use of these options.

If someone needs the functionality, it can easily be added back using a

in the foot.

Removal of the translations for the config strings can follow after this
has been merged.
