Resolves issue#827, where `timeUntilAlarm` wasn't working as Expected

[Gaurav-Kushwaha-1225]

Description

Now, the alarm scheduling logic incorporates the alarmDate parameter into the timeUntilAlarm function for the calculation of a non-repeating alarm that's scheduled after some days.

Also, you can refer to this small discussion #gsoc-ultimate-alarm-clock > @ 💬, regarding the Repeat and Rings On feature, where it was proposed to disable the Rings On when Repeat is enabled, or vice versa.

Proposed Changes

• Added alarmDate Parameter: The timeUntilAlarm function now accepts an additional alarmDate parameter to handle date-based alarm scheduling.

• Controller Updates: Now, if Rings On is enabled or selectedDate != DateTime.now(), then make the Repeat as Never or repeatDays = [false, false, false, false, false, false, false]. Or, vice versa.

Fixes #827

Screenshots

In the video below, the calculation for Rings in __ is now accurate for alarms set on a specific date. And, selecting both a specific date alarm and a repeat alarm is not possible, since enabling one will disable the other.

In the latest commit, I also resolved a problem in calculating the rings in value for an alarm, set for repeat on a day which is the same as today.

Like in the video below, today is Friday, and 'Rings in' was giving "Rings in No upcoming alarms", instead of "Rings in 6 days", when set the repeating day as Friday itself.

Hii @Gaurav-Kushwaha-1225 take a look at PR(#830) which has good UI/UX and solves the ringson issue , rings in duration

Hi @mahendra-918, I saw your PR (#830) — it looks good!

However, I noticed that you've made some significant changes to the UI as well. The original issue #827 you addressed was specifically about the bug in the timeUntilAlarm method that calculates the Rings in __ value.

If you are planning to implement any additional ideas, it would be better to discuss them first in the Zulip discussion group to get some feedback from mentors and community members.
