Merge application layer for handling post retrieval use cases

[zigzagdev]

Description

This PR finalises and merges the Application layer logic responsible for coordinating post-related retrieval flows. It introduces the GetOthersAllPostsUseCase, which delegates query operations to the GetPostQueryServiceInterface, returning paginated data encapsulated in a PaginationDto.

This marks the integration of the application logic responsible for retrieving public posts made by users other than the currently authenticated one.

---

What’s Included

• GetOthersAllPostsUseCase:

• Handles input parameters: userId, perPage, currentPage

• Delegates query to GetPostQueryServiceInterface::getOthersAllPosts

• Returns PaginationDto composed of PostEntity instances

• Application-layer isolation:

• No knowledge of Eloquent or database structure

• Works purely with DTOs and interfaces

• Supporting test (in separate PR or module):

  • Ensures delegation to the query service
  • Validates type and structure of returned pagination data

• Test classes should be located in the tests directory and use the Tests namespace to avoid mixing test and production code.

• The mock allows currentPage to be zero, but pagination typically starts at 1; consider changing the condition to $arg > 0 to match expected input constraints.

                Mockery::on(fn($arg) => is_int($arg) && $arg >= 0) // currentPage

[nitpick] There's an extra space between readonly and the type declaration; consider normalizing spacing to follow PSR-12 style.
