Eliminate DOM hooks

[Corb3nik]

Convere the following locations into official SDK calls:

/scope hooks into the form header
/filter hooks into the form header
/tamper seems broken in the latest Caido versions but it used to hook to the form header
/search and /http-history hooks into header of the Request Editor card

We also need the selected element of that page

Mostly fixed in 930e73e
Will keep open as there are still some DOM hooks to be replaced
