Refactoring / updating the schedule view

[cycomachead]

For now, we want 1 or 2 new pages or to refactor existing one?

• a compact view, something kind of like: https://sigcse2026.sigcse.org/program/program-sigcse-ts-2026/Detailed-Table
• we have this with the full calendar list view. Should we just improve that and make it more usable?
• full calendar and the All Events page use different timezone mechanics, these should be unified.
• the filtering of event types could be more clear.

This provides a nicer example of implementing filters on a page.
