* fix(web-ui): load v3 tab content deterministically The v3 dashboard tab panels loaded content via hx-trigger="revealed", but the panels are shown/hidden with Alpine x-show (display toggling), which never produces the scroll event htmx's "revealed" handler waits for. loadTabContent tried to force it with htmx.trigger(el, 'revealed'), but "revealed" is a synthetic scroll/observer trigger, not a dispatchable event, so that call is a no-op. The result was an intermittently blank panel - content appeared only when htmx's native reveal scan happened to fire on its own. - Replace the trigger with a custom "loadtab" event that nothing fires spontaneously (0% native firing). - Load panels via htmx.ajax, which issues the request directly and works even before htmx has processed the element's triggers - unlike htmx.trigger, which is lost if dispatched before processing. - Poll for htmx when it hasn't finished loading from the CDN instead of relying on a one-shot htmx:ready event that can be missed. - Stamp data-loaded on the request promise so each panel loads once. Verified in the emulator web UI: overview loads on every reload, tabs lazy-load on demand, and revisiting a tab does not refetch.

Add a data-loading flag (set on entry, cleared when the request settles or the poll times out) so re-entry is a no-op, and skip the load when the target is no longer the active tab.
