Pull request overview

This PR updates Get-CalendarDiagnosticObjectsSummary to make the fast (AppointmentRecurrenceBlob-based) exception collector the default for recurring meetings and to reduce the default exception lookback window to 3 months to address slow (hours-long) collections.

Changes:

• Switches recurring-meeting exception collection to default to the fast collector and limits default exception date collection to the last 3 months (unless overridden).
• Introduces/updates switches intended to control exception collection behavior (e.g., -ClassicExceptions, -AllExceptions) and updates output strings accordingly.
• Adds additional role-classification / Excel workbook coloring behavior (delegate-related) beyond the exception-collection change.
