Migrate according to new hooks architecture in PR#12879

[ozer550]

Summary

Updated kolibri-app to work with Kolibri PR #12879, which removed the old app plugin and replaced it with a hook-based system.

• Removed old plugin dependencies: deleted references to the removed plugin.
• Updated URL generation: switched to the new function for building initialization URLs.
• Removed file sharing and metered connection code that wasn’t implemented.

Reviewer guidance

For Ubuntu:

• Install system dependencies:
  sudo apt install python3.10-venv python3.10-dev
• Create and activate a virtual environment:

   /usr/bin/python3.10 -m venv venv-system   
   source venv-system/bin/activate
  

• Install build dependencies:
  make dependencies
• Download the Kolibri wheel from PR #12879:
  • Go to PR #12879
  • Download the .whl artifact from the CI build
  • Copy the wheel file to the whl/ directory (in kolibri_app):
    mkdir -p whl
cp /path/to/downloaded/kolibri-*.whl whl/
• Install the wheel:
  make install-whl whl=whl/kolibri-<version>.whl

One thing that needs to be retained.

We still need to enable the plugin from this repository! Just not the kolibri one.
