Add checksearch functionality to validate online search availability
for multiple streaming services including AnimeON, Bamboo, CikavaIdeya,
Makhno, Mikai, StarLight, UAKino, UaTUT, Uaflix, and Unimay controllers.
Each controller now supports a checksearch parameter that returns
appropriate responses when online search validation is enabled.
Add StripLampacArgs method to remove account_email, uid, and nws_id
parameters from streaming URLs before processing. This enhances privacy
by preventing user identification data from being passed through to
external services. The change is applied across all controllers that
handle stream URL generation.
