dashboard: don't yank the form away while operator is typing

every refreshState tick does root.innerHTML = '' across the managed
sections, which destroys any focused input. detect the case before
re-rendering: if document.activeElement is an INPUT / TEXTAREA /
SELECT inside one of the managed sections, skip this tick and try
again in 2s. eventually the operator blurs and the refresh lands.

managed section ids: containers / tombstones / questions / inbox /
approvals. msgflow + message-flow SSE rows don't have inputs so
they're not affected.
