Feature/backend data integration

[deb-coder-man]

What does this PR do?

Replaces static mock data and CMS REST API calls with direct Supabase queries for the three public-facing data collections: events, execs, and sponsors.

Supabase client

• Added @supabase/supabase-js to the web package
• Created a shared supabase.ts client driven by NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY env vars

New data hooks (web/src/hooks/)

• useExecs() — fetches exec members sorted by year descending; joins the media table on photo_id to resolve photo URLs in one query
• useSponsors() — fetches all sponsors sorted alphabetically; joins media on logo_id for logo URLs
• useSponsorOfTheWeek() — fetches the single sponsor with is_sponsor_of_the_week = true using .single()

Refactored hooks

• useEvents / useUpcomingEvents / usePastEvents — switched from fetchFromCMS to Supabase; cover image joined from media via cover_image_id

Updated types (web/src/types/)

• Event, Exec, Sponsor types updated to snake_case column names matching Payload's PostgreSQL schema (e.g. is_upcoming, cover_image_id → joined cover_image, is_sponsor_of_the_week)

UI connected to live data

• ExecGrid — replaces execData.ts static array with useExecs(); shows 8 animated pulse skeletons while loading, falls back to /mascot.png if no photo uploaded
• PastEventsSection — replaces pastEvents static array with usePastEvents(); maps Supabase Event rows to the PastEvent shape via a toPastEvent helper; search and category filters work against live data; shows skeleton cards while loading

pastEventsData.ts — static pastEvents array removed; PastEvent/EventFilter types, EVENT_FILTERS, and new CATEGORY_TO_TAG map kept (still used by PastEventCard and PastEventsSection)

Is this array only used for skeleton card indexing, cuz if so no need to create a hardcoded array. I think there are easier ways to just create an array of increasing numbers.

[henryhlly]

Why do we need a mapping function the PastEventCard should handle generic events?

This is way better, good shit dave, just a couple of questions then Ill approve
