Web dashboard v2 step 3: dashboard restyle

Restyle every template under src/web/templates/dashboard/ plus the shared
partials _candidate_row.html, _signals_table.html and _pagination.html with
Tailwind utilities and the design system step 2 built, so the dashboard reads
as the sans-serif instrument-panel half of the same publication as the reader
pages: a page header on every page, stat tiles, compact tables with sticky
heads inside .scroll-x, tinted badges, one inline filter form per page,
settings groups with a sticky save bar, job cards, a scrolling journal block
and a rating widget that fits inside a table cell.

tailwind.css gains the dashboard vocabulary (.page-head/.page-desc/
.page-actions, .tiles/.tile*, .cell-wrap, .scroll-x.tall, .filters,
.pager/.tabs, .setting*/.save-bar, .disclosure, .sparklines/.spark-figure,
td .rating overrides, tr.superseded) plus a styled <meter> and a disabled
control state. Renames class="inline" to form-inline: Tailwind emits an
.inline display utility that was beating form.inline's layout.

Three small backend changes: job cards show the status and time of their last
run (attach_last_runs, no extra query, unit-tested); the Stats page passes
"stats" as its nav key so the admin nav no longer highlights Overview; and the
settings load-error banner drops its "! " prefix, with its assertion updated.

cargo test: 477 passed. npm run css:check clean.
