377 backend schedule logic fix

[hadiafifah]

finished updating logic to check end time and order accordingly

[hadiafifah]

Added #422 (branch name 391) changes to this branch because it needed fixes from this ticket to be fully finished. Feel free to disregard that PR.

On top of backend changes from this PR, and the visual changes from #422, I also refactored /schedule/page.tsx into reusable components because it was starting to get really chunky. These are the main changes:

File structure changes

• page.tsx was reduced to mostly composition/presentation
• Added dedicated hooks for schedule logic (useScheduleData.ts and useActiveDaySync.ts)
• Added shared schedule modules to reduce duplication (constants.ts, types.ts, and groupedEntries.ts)
  Broke rendering into reusable components:
• ScheduleControls.tsx
• DayNavButtons.tsx
• DaySection.tsx

Data/state refactor changes

• Centralized schedule state in useScheduleData:

1. active tab/day/filter state
2. mobile filter drawer state
3. grouped entries by day
4. add/remove personal schedule handlers
5. initial-load/error flags

• Centralized day navigation sync in useActiveDaySync:

1. click-to-day smooth scroll
2. scroll-based active-day detection
3. temporary click lock/pending-day logic to prevent highlight jitter

• Centralized data transformation path:

1. event data + personal data grouped by Pacific day key
2. filter application moved to shared grouping utility
3. deterministic sort with start-time + end-time tiebreak handling
4. grouping by time label reused for both days

Pull request overview

This PR refactors the hacker schedule UI/data flow and updates time-based schedule logic so “next”/“live” determinations account for event end times, while also reorganizing schedule rendering into reusable hooks/components.

Changes:

• Added shared schedule types and grouping utilities (group by day + start time, with end-time tie-breaking).
• Reworked the schedule page to use a new useScheduleData hook and new controls/sections components (scroll-synced day nav).
• Updated “next schedule” and schedule sneak peek logic to use end-time aware live/upcoming calculations and countdown labels.

Nice job cleaning up schedule page! Pretty clean breakdown of components.
Moving forward please move hooks and types to the appropriate folder & some brief comments in the backend-related files would be nice for readability

Added:

• schedule page & sneak peak requested fixes
• useScheduleSharedNow for consistent seconds update
