Move the remaining panel explanations into tooltips

A node setting's description comes off the backend JSON schema, so every
node type's panel still printed a paragraph under each field. It moves to
the field label, which is the change that makes the node panel read as a
list rather than a page.

Alerts, Modules and Remote access follow the same shape. A page keeps a
one-line description under its h1 — a page is arrived at rather than
scanned — and the rest goes behind the heading's tooltip.

Verified on the running stack: the tooltip opens on tap in the phone sheet
and on hover on the desktop panel.
