Bookings: Enable searching in service/event filter

[itsmeichigo]

Part of WOOMOB-1240

Description

This PR adds the search capability on the Service / Event filter for bookings. Tests for SyncableListSelectorViewModel have also been added.

Test Steps

1. Log in to a CIAB store with existing bookings.
2. Navigate to Booking tab > All > Filter > Service / Event.
3. Confirm that a search bar is now available at the top.
4. Enter any keyword and confirm that the list is updated with search results.
5. Enter keywords that don't match any products. Confirm that the empty state is displayed.

1. Not related to the PR: The top divider of the top cell interferes with the header bottom line. Probably the bottom divider of the bottom cell is not needed either:

2. I'm not sure if I fully understand the product search results and keywords logic. But trying just the substrings of service names in search gives unexpected results. For example if testing in our shared CIAB site and entering the "Ro" search term I can see both "Room Rental" and "Hair Salon Appointment". Entering "P" also reveals both results. "Re" also both results.

Looks good and readable. How about making it shorter?

var predicates = [syncable.createPredicate()]
if !query.isEmpty, let searchPredicate = syncable.createSearchPredicate(keyword: query) {
    predicates.append(searchPredicate)
}
resultsController.predicate = NSCompoundPredicate(andPredicateWithSubpredicates: predicates)

Much better - done in ebae5bf.

Thanks for the feedback!

The logic is that we assign results from remote with the keywords that yield the response. Your observation is correct, but I see the same thing in the remote responses via Proxyman. This suggests a bug in the backend code, I'll raise the issue in the channel asking the devs. This seems to be an issue with the product search - we're currently leaving search_fields field empty. According to the API doc, we would need to set the field to name only if we want to match only names. I'll need to confirm with the team the expected behavior and update the search behavior accordingly - but I'll do that in a separate PR.

This PR is ready for another look.

LGTM. Thx for the update.
