feat: apply view filters live as the user types

Filter text fields used AjaxFormComponentUpdatingBehavior("change"),
which only fires on blur/Enter, so the filter required pressing Enter.

Add a reusable FilterUpdatingBehavior that listens on the "input" event
(fires per keystroke) with a 300ms debounce so rapid typing coalesces
into a single request. Swap it into all filter fields.
