Apple Health Integration: Integrate Mood Log with Apple Health "State of Mind"

I suggest integrating Habitify's mood logging with the Apple Health "State of Mind" feature.

Currently, mood data remains isolated within Habitify. Enabling read/write sync would allow users to:

1. Centralize mental health data within the Apple ecosystem.

2. Correlate habit completion data with native Apple Health metrics (e.g., sleep, exercise, time in daylight).

3. Eliminate redundant logging for users who already track emotions in Apple Health.
