4ec42fdbc0 Add cups unit option for kcal/cup measurements
Features:
- Add cups as a unit option that only works with kcal/cup energy measurements
- Cups button is disabled with tooltip when kcal/cup is not selected
- Auto-select cups when user selects kcal/cup as energy unit
- Auto-switch to appropriate units when changing energy measurement types
- Calculate cup amounts directly from calories without density assumptions

Fixes:
- Ensure cups display correct values immediately upon auto-selection
- Fix "Per day" radio button to be pre-selected when feeding config becomes visible
- Handle empty unit values with failsafe fallback to active button

Technical details:
- Direct calorie-to-cups conversion bypassing gram conversions
- Pre-calculate cups values in food breakdown for efficient display
- Set unit before updating calculations to avoid timing issues
- Added CSS styling for disabled button state across all themes

8758ac1dbc Add per-meal feeding frequency feature
- Added feeding configuration section with daily/per-meal toggle
- Implemented meals per day selector (1-10 meals)
- Updated all calculations to support per-meal division
- Dynamic unit labels change from "/day" to "/meal"
- Added helpful meal count display for multi-day calculations
- Proper dark theme support for new UI elements
- Mobile responsive design for feeding controls
- Centered meal input group for better UX

This feature allows users to easily switch between viewing daily food amounts
and per-meal portions, making feeding schedules more practical to follow.
