Cleanup and optimize dependencies

[andreia-ferreira]

Towards #3365

In order to update the current E2E test the code needs to take into account Compose elements that were added in the meantime. However, adding the dependency and the composeTestRule in the e2eTest module would cause a NoSuchMethodError crash.

This PR fixes that by replacing androidx.fragment:fragment-testing with fragment-testing-manifest. This ensures the tests continue to have the necessary components while avoiding dependency conflicts and runtime crashes.

Additionally a couple of improvements were done:

• Use BOM for compose, coroutines, and serialization so that all related libraries are aligned to compatible versions, reducing the risk of dependency conflicts and simplifying version management
• Remove unused dependencies

In order to make sure that no issues were introduced by this, a general sanity check of the app was performed.
