inbound-antispam-panel: Inbound > Log and Inbound > Filter lists

Step 6/12 of docs/plans/inbound-antispam-panel.md. Written by a Sonnet
subagent from the mockups, reviewed and corrected by me.

GET /inbound/log - the journal a page at a time (50), filtered by
domain, decision and day; QueryInboundSpam / CountInboundSpam with the
viewer's inbound domains as the scope. The global role reads all of it
and gets "Deny sender" / "Allow sender" links into the lists; a user
with the domain role reads the rows of the inbound domains assigned to
them, without the links. The plan said global-only for the journal;
the accepted mockup and 2.0's delegation of Inbound say otherwise -
recorded in the plan as built.

GET, POST /inbound/filter-lists and POST .../{id}/delete - global role,
404 otherwise. Add form (prefilled from the query), the two lists with
Remove as the kit's row action, and "Where the lists go" with the
filter's state and when the maps were last written
(Lists.LastWritten). A refused or duplicate entry is 422 with the
message and what was typed.

Server > Settings: "Keep inbound log rows, days" with the relay on.
Help: Inbound log, Filter lists. Navigation: Log for everyone who sees
Inbound, Filter lists for the global role (Shell.ShowFilterLists).
Status tags accept / reject / tempfail join the kit's mapping.

Tests: page fixtures for both screens, held to outlines.json; view and
handler tests (both roles, filters, paging, relay off, add / duplicate
/ invalid / delete, map file content, settings field, help). e2e reads
the journal from the page instead of the database and adds and removes
a deny entry through the panel, reading deny_domain.map after each.

Seen: both pages and Settings rendered from their fixtures and compared
with the mockups side by side (headless Edge, 1360 px) - same layout
and wording.

Checked on the test server, uncommitted tree: go vet ./... ok,
go test ./... ok (22 packages), make e2e ok.
