refactor: fix event edit page code review issues (#87)

- Extract EditEventCard component to eliminate duplicated edit form
- Add edit form to non-schedule event types (bracket events)
- Move actionData feedback above debug cards for better UX
- Guard "Add Result" form from showing on playoff_game events
- Fix isPast date comparison to be safe for Date or string types
- Remove unused qpConfig/qpStandings destructuring
