Implement finished lessons list

[catileptic]

The Figma document contains the entire UI of the project.

You can export any image (asset) directly from Figma. Here's how.

Please do not try to recreate the UI design exactly. Prioritize using de default UI mobile components, and following the material design guidelines. The UI objects should be positioned roughly the same as in the Figma screens.

The mobile flow can be found in the project Wiki.

Please define related colors and text & button styles in the corresponding values files. Please extract all text values in the corresponding xml files so we can easily adjust them. <3

When a user clicks on any of the lesson theme names, or the Lecții parcurse button in their profile page, under Rezultate, they should be taken to a list that contains all the lessons they have finished (filtered by theme, if the user clicked a theme name). These lessons will be pulled from the appropriate backend endpoint.

This list should be similar to the default lessons list.
