feat: optimize code

[eramitgupta]

Changes Made:
Extract Variables: Extracted search, sortBy, direction, and published from the request to make the when conditions more readable.

Concise when Conditions: Used shorthand fn syntax for inline functions.

Simplified view Call: Used compact('posts') for a cleaner way to pass the variable to the view.

Script @test:type-coverage was called via test
