docs: draw every panel screen in the accepted redesign direction

Stage 2 of the panel redesign. Direction C (Bulma) is the base — the
important things in view, details one or two clicks away — with A's
postal signature (postmark verdict, numbered mono section heads, the
stamp's perforated edge) and B's icons. 29 screens under
docs/assets/panel-redesign/panel/, linked into a click-through.

Overview keeps verdicts only; the process, socket and interface tables
move to a new Server > Health page. The own password becomes Account,
queues are drawn as tables (needs postqueue -j), and Inbound gets its
own Log and Queue. Every page is one of three layouts, so none picks
its own width.

Pages are built from panel/src fragments by panel/build.py so the navbar
lives in one place; the built HTML is committed. The cover sheet now
leads with the screen map and keeps the three stage-1 directions below.

Mockups only; internal/web is untouched.
