fix(frontend): Make input layout & padding consistent (#9170)

There are a few hardcoded margins and padding in the block input layout,
causing the input to sometimes overflow or be used inconsistently.

### Changes 🏗️

* Make padding consistent between left & right, top & bottom.
* Remove hard-coded margins.
* Match the hardcode negative margin for the right node handle to the
left node handle.
* Make the input box take the full width.
