refactor: simplify DataFactory and PwaService dependencies

Remove unnecessary parameters from DataFactory and PwaService 
constructor. The changes streamline the service initialization 
process by eliminating the unused HttpClient dependency in 
DataFactory and adjusting PwaService to inject HttpClient 
directly. This improves code clarity and reduces complexity.
