Bug in MonthlyCalendar

[SummerTimeForAll]

Hello,

I believe I have found a bug in the MonthlyCalendar class,
in the method getNextIncludedTime(long timeStamp).
The while loop is based on the test isDayExcluded(day) (line 216).
The problem is that this method does not verify whether the attached baseCalendar is in sync with the day found.
Instead, the isTimeIncluded(long timestamp) method should be used.

This issue also appears in the WeeklyCalendar and possibly in other classes.

Example :

    MonthlyCalendar mcal1 = new MonthlyCalendar();
    mcal1.setDayExcluded(11, true);
           
    MonthlyCalendar mcal2 = new MonthlyCalendar();
    mcal2.setBaseCalendar(mcal1);
    mcal2.setDayExcluded(10, true);
    
    testTime = "10/01/2025 08:30:00";
   
    SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
    dateResult = new Date(mcal2.getNextIncludedTime(sdf.parse(testTime).getTime()));
    System.out.println(sdf.format(dateResult));

Result :
11/01/2025 00:00:00

  should be 12/01/2025 00:00:00
