Augment the query bar with a refresh/cancel option, group the Show and Sort options, and add a "locale/UTC" time selection - #3110

Large audit stores easily reach nine-digit totals; 'Showing 100 of
158736340 result(s)' is unreadable. Both numbers now go through
Intl.NumberFormat with the user's locale (158,736,340 / 158.736.340).
ResultsCount is shared, so the heartbeats views and the throughput
queue list pick this up as well.

The refresh cluster occupied its own row above the filters; it now sits
right-aligned inside the query bar so the whole query surface is one
row. While a query is in flight the button flips from Refresh to an
enabled Cancel that aborts the running query through the store; the
abort propagates through ServiceControl and terminates the
database-side query. Once results land, the results line reports what
they cost: "Showing 100 of 158,736,340 result(s) · took 2.7 s". The
timing is forgotten with the results when the view is left.

ActionButton hard-coupled loading to disabled, which would have left
the button dead exactly when a user most wants an escape hatch; it
gains disableOnLoading (default true, existing uses unchanged) and the
refresh/cancel button opts out. The spec stubs ActionButton with the
real disabled semantics so that coupling can't silently return.

… screen readers

While auto-refresh is armed and no query runs, the refresh arrow is
replaced by a small ring that depletes toward the next refresh, with
the remaining seconds as its tooltip; during a query the button shows
the usual spinner. The ring mirrors FontAwesome's icon geometry:
ActionButton gains a named icon slot so custom icons are flex children
with the same centering as FAIcon. Reduced motion disables the
animation.

The ring is purely decorative (aria-hidden). The countdown reaches
assistive tech as a visually hidden "Next auto refresh in N seconds"
timer that describes the button, read together with it rather than
announced on every tick; the button keeps its stable name "Refresh".
The wording test runs on a frozen clock so the 250 ms ticker cannot
race it.

…nstead of a clock

The refresh control is one split button: the refresh/cancel action on
the left with a fixed width for both states, and a compact segment on
the right showing the active interval as "Off", "5s", "1m", "1h" that
opens the interval menu. The separate "Auto-Refresh: Every 5 seconds"
selector is gone, which frees a good part of the query bar; the menu
spells each interval out and the segment carries the full wording as
its accessible name.

The elapsed-time clock in the Cancel label is gone (it changed the
button's width on every tick). What it was there to convey is now said
in words: once a query has been running for five seconds the results
line shows "Still running · a narrower time range makes the query
lighter" on its own line under the result stats, and drops it when the
query ends. Show, Sort and Times are pinned to the right of that line
and never wrap.
