feat(web): order the shipped presets, and edit one on its own screen

The picker listed presets alphabetically by id, so the shipped set read
cordis, minimal, standard — reverse order of capability. A preset may now
declare `order` in its metadata; the shipped three declare 1/2/3 and read
standard, minimal, cordis. A preset that declares none sorts behind those
that do, then by id, so authored presets stay stable.

Editing had nowhere good to live. Inside a card it was squeezed into a
~268px column; hanging off the end of the grid it was orphaned from the card
it edits. It now replaces the list: a back link, what is being edited, and
the form at full width. One thing on screen at a time, which is what the
form's height wanted all along.

Cards in different grid rows sized independently, so a short description made
a short card. `grid-auto-rows: 1fr` makes every row the same height.

The trust badge lost its pill when the card CSS was rewritten, and `In use`
never had one; both are tags now. Icon labels moved from `title` to a drawn
tooltip — the native one waits about a second, which reads as nothing
happening.
