Fix noon/midnight time display by deriving from numeric time values

[Copilot]

The schedule page displays times using "12:00n" for noon and "12:00m" for midnight—a non-standard convention. These should use standard AM/PM format.

Changes

• ScheduleService.formatTime(): Updated to derive time display from the <time> XML element (minutes after midnight) instead of using <time_str>. Converts numeric values to 12-hour formatted strings (e.g., 0 → "12:00am", 720 → "12:00pm")

  formatTime(minutes: number): string {
    const hours = Math.floor(minutes / 60);
    const mins = minutes % 60;
    
    let displayHour = hours % 12;
    if (displayHour === 0) {
      displayHour = 12;
    }
    
    const ampm = hours < 12 ? 'am' : 'pm';
    const minuteStr = mins === 0 ? '00' : mins.toString().padStart(2, '0');
    
    return `${displayHour}:${minuteStr}${ampm}`;
  }

• SchedulePage: Updated to pass show.time (numeric) instead of show.time_str to formatTime()

• Tests: Added comprehensive unit tests for formatTime() with numeric inputs and integration tests verifying display in SchedulePage

• Mock data: Added noon/midnight show examples for test coverage

What the ScheduleService should probably do is derive the time display from the <time> XML element (which represents minutes after midnight) to generate the time string, rather than using <time_str> at all.

Done. Updated formatTime() to derive the time display from the <time> XML element (minutes after midnight) instead of using <time_str>. The method now converts numeric values like 0 → "12:00am" and 720 → "12:00pm". (commit: 96acf61)
