feat: Enhances mood management capabilities

Updates `value` field validation to ensure positive integers,
preventing non-positive mood values in the model.

Adds functionality for creating new moods through the UI by
introducing `MoodCreateView`, integrating it into URLs and
enhancing the mood list view with creation options.

These enhancements improve data integrity and user experience
in mood management.
