Fixes #38252 - Display boolean searchable_value as true/false in search field

[lfu]

searchable_value is a text field in DB. So boolean value is saved as t and f in the DB instead of true and false.
We will present these boolean values as true and false in the search field with this commit.

Test Steps
Hosts - Content Hosts, and in the search field, you can add a query

Before
params.host_registration_insights = f and params.host_registration_insights = false
Both "false" and "f" will be presented automatically on Satellite . But you get accurate response only when selecting "f".
I don't see params.host_registration_insights = false displayed on a devel box.

After
Only params.host_registration_insights = false for false and params.host_registration_insights = true
