[6.12.z] - remove the all nailgun imports from UI folder

[omkarkhatavkar]

Problem Statement

We are using the direct imports from the nailgun rather than directly using from target_sat

Solution

Direct Imports Removed: We've cleaned up our codebase by eliminating direct imports from the Nailgun package.

Using target_sat, module_target_sat, class_target_sat: Modified the API calls and using the target_sat.api. pattern for all API calls.
