Feat: New UI global search

We are introducing a new search UI that providers a lot more space
for users via a large centralized modal and providers various filters
which can by applied by adding various chips on the UI.

For example, users can now filter their search or scope it by limiting the results
to specific apps, time period and people by apply the appropriate filters on the
new UI, previously filters where applied using text in the search box by prefixing
with `::`.

Resolves: #39162
