FacetWP 4.2.12

- layout builder - added facetwp_builder_dynamic_tags hook to create new Dynamic Tags without having to add a hidden item
- admin UI - replaced FontAwesome with in-house SVG handling for faster loading
- query detection - only intercept the *identical* query (it was too lenient before)
- refactored SearchWP integration for FacetWP 3.6+
- vendor libs (vue, flatpickr, etc)

- incorrect post types were appearing on home listings
- re-added is_archive to query detection check
- WooCommerce - ensure that $product exists before calling its methods
- WooCommerce - apply new tooltip styling to WC admin settings
- added FWP()->is_filtered and FWP()->filtered_post_ids convenience props

- more tweaks to the query detection algorithm (third time's the charm, right?)
- hide the WP admin bar during ajax refresh, to prevent rare JSON parsing errors
