Implement task move via Drag & drop (or move up/down actions)

[opatry]

This should be a refinement of Move to top action.

• Provide DAO API to get tasks between 2 positions (which would be the tasks on which to update positions)
• Open repository (and ViewModel counterparts) APIs to move at given position and/or move up/down
• Add unit tests
• Integrate on UI side (move up/down menu would be quicker)
• Integrate Compose drag and drop/list reodering
• Evaluate drag task to another list using Compose drag and drop

Tip

See JetBrains/compose-multiplatform-core#1510, to achieve move from list to another.
Doesn't handles the reordering within the same list.
