fix: one docs button per page, and unwedge the inference one

The package manager shell and its hosted pages both carried a ? button, so the
console page showed two stacked in the same corner. The shell no longer claims
one; the package list page owns its own, matching the console and install-detail
pages.

The inference button also sat inside the connection cluster with 2px spacing;
it now follows that cluster, ahead of the overflow menu. Bumps the control's
padding to a 28px hit target.
