Refactor SnackBar API (#9276)

Resolves #9259

## Changes
- Simplified API by removing `title` prop in favor of required `message`
prop
- Added `detailedMessage` prop for supporting additional context
- Updated styling for improved message display
- Renamed `defaultTitleByVariant` to `defaultAriaLabelByVariant` for
clarity
- Adjusted header alignment and icon styling

## Testing
- [x] Verified all SnackBar variants display correctly
- [x] Tested with and without detailed messages
- [x] Checked responsive behavior
