Null-Pointer Crash on Empty Meeting Lists

[aniket866]

Closes #639

• File Reference: CommunityMeetingsCardGrid/index.tsx

• Code Pointer:

  for (let i = 0; i < 2; i++) {
    let meeting = MeetingDropdownOptions.shift();
    communityMeetingsData.push({
      date: meeting?.date,

• Technical Reason & Impact: The component shifts items out of lists without validating their lengths first. If an array is empty or holds a single item, shift() yields undefined. Consequently, SubcardGrid passes undefined to the Date constructor, returning NaN. DayOfTheWeek then returns undefined, which gets passed into children components, producing empty links and text sections.
