Fix today's habits timezone calculation and include entry data

- Calculate today based on user's timezone instead of always using UTC
- Include habit entry in response if it exists for the current day
- Update GetTodaysHabitsHandler to fetch and return entry information
- Add entry field to TodaysHabitDTO and TodaysHabitResponse
- Update tests to reflect new behavior of including completed habits
- Add test for habits with value entries
