audit 4: log paging at its edges, NaN refused, a red rate limit, recalculation asks, reload writes all

Step 4 of stage 4 (L10, L11, L13, L18, L19 and a row of
review-2026-08-followups):

- The Outbound log counts first and clamps the page to the last; a number
  too large for an int (strconv's ErrRange with the largest int) is the
  last page on both logs. Tested at the edges: first, last, past the last
  however far, nonsense, an empty log asked for page 5.
- checkAutoMultiplier is "not within", so NaN and the infinities are out.
- rate-limited is red (components.go; the mockup first, 643892a).
- data-unsaved on both recalculate buttons: panel.js asks on submit
  (ev.submitter) when a field of the page differs from what it was drawn
  with; testdata/unsaved_test.js under TestPanelJS.
- HandleReload writes what a restore's first start writes - the filter
  lists and the DMARC maps too - and a failed step is an error flash on
  Health that names it, not plain text; the success flash says what was
  written.

Tested on the test server: go vet + go test of 25 packages, make e2e (all
pass, 695 s) on this tree.

+- **Reload configuration writes everything a restore's first start writes.**
+  The button on Server › Health left the DMARC report maps and the filter
+  lists out while it said the configuration was regenerated; it now writes
+  them too, and a step that fails is a message on the page that names it,

+  past its end - a link kept while old rows were pruned, or a number typed.

+- **A message refused under a rate limit was a grey tag** beside its two
+  red siblings, *wrong From* and *wrong client*. It is red (audit

+- **Recalculate rate limit dropped what was typed on the page.** The button
+  leaves the page; when a field holds an edit not saved yet, it now asks
+  first (audit 2026-10-12, L19).
