docs: draw the roadmap's screens in the panel design

Four screens for open roadmap items, all built from existing components:
Inbound > Filter lists (allow / deny, where the maps go) and an adjusted
Inbound > Log (client, decision, engine and reason, Allow / Deny sender)
for inbound-antispam-panel; Inbound > Quarantine, list and held message
with Release beside a danger-zone Discard, for inbound-quarantine; and
Server > Preflight, a verdict postmark over a table of checks with a
"what to do" column and a test e-mail form, for preflight.

A mockup is the target look, not a decision to build: each item keeps
its status, and quarantine's open questions stay open - the mockup only
assumes answers to them. The paths join the plan's Routes table, the
quarantine and preflight plans link their mockups, and the components
page maps the quarantine decision to a tag. 33 screens; lint clean.

 ### Added
 
+- Panel redesign, the roadmap's screens: **Inbound › Filter lists** and the
+  adjusted **Inbound › Log** (client, decision, engine and reason; *Allow /
+  Deny sender*) for inbound-antispam-panel, **Inbound › Quarantine** (list and
+  held message with Release / Discard) for inbound-quarantine, and **Server ›
+  Preflight** for preflight — all from existing components; 33 screens. Their
+  paths join § Routes; the quarantine and preflight plans link their mockups.
+  A mockup is the target look, not a decision to build: each item keeps its
+  status, and quarantine's open questions stay open.
 - Panel redesign, two owner decisions recorded in
   `docs/plans/panel-redesign.md`: **no compatibility** — the redesign is
   `2.0.0`, old paths are removed without redirects, the SQLite migration chain
