feat(http): implement token refresh mechanism and JWT invalidation in new http feature

[marfavi]

Description

This PR adds a token refresh mechanism to the http layer so expired JWTs are renewed transparently, without requiring the user to log in again. There is a cyclic dependency between the token refresher and AuthCubit (which handles logout logic), so this is fixed with an AuthCubitHandle.

HTTP-related files are now moved into a dedicated http/ feature folder.

Type of Change

• ✨ New feature (non-breaking change which adds functionality)

• ❌ Breaking change (fix or feature that would cause existing functionality to change)
• 🧹 Code refactor

Pull request overview

This PR implements a token refresh mechanism for the HTTP layer, allowing expired JWTs to be automatically renewed without requiring user re-login. It also reorganizes HTTP-related files into a dedicated http/ feature folder and introduces a cyclic dependency breaking pattern using AuthCubitHandle.

Changes:

• Implements TokenRefreshAuthenticator to automatically refresh expired JWTs on 401 responses and retry failed requests
• Adds AuthCubitHandle to break the cyclic dependency between HTTP layer and authentication logic
• Introduces a debug-only JWT invalidation feature for testing token refresh behavior
• Reorganizes HTTP components into a dedicated feature folder with a barrel export file
