Add a description multiline text field to both Habit Groups and individual Habits.

For each Group, the description should clarify its overall meaning and the areas it encompasses. For example: Group: Mind & Personal Growth - Description: Mental well-being, emotional intelligence, self-awareness, discipline, habits, learning, knowledge, creativity.

Similarly, each Habit could have its own Description field to clarify exactly what the habit means and what behavior is intended. This would provide greater awareness and consistency, especially when a habit could otherwise be interpreted in different ways.

For example: Habit: Read - Description: Read for at least 20 minutes each day to expand knowledge, stimulate curiosity, and support continuous intellectual growth.

This makes the habit-tracking system more meaningful, intentional, and easier to use consistently.
