Pull request overview

This PR updates 2026 track/panel data and validation, improves the admin CSV ingestion UX by surfacing processed team rows + contact info, and updates hacker-facing submission guidance (plus HackBot knowledge) around Devpost track selection (Tracks 1–3 vs Opt-in Prizes).

Changes:

• Add/adjust MongoDB collection validators and track sets for 2026 (teams tableNumber type, panels track list).
• Extend CSV validation to collect per-row contact info and render a processed-teams table in the admin CSV page.
• Update submission instructions + HackBot knowledge to clarify HackDavis tracks vs Opt-in prizes; add 2026 test CSV data.

Panel judge assignment now prioritizes domain specialists over unmatched judges.

The bug:

Array.indexOf returns -1 when the item isn't found, which is less than any valid index (0, 1, 2…), so judges with no matching specialty were sorting to the front and getting picked first over actual domain experts. Fixed by mapping -1 to Infinity so unqualified judges always fall to the back of the sort rather than the front.

Eg:
If a panel is track AIML:

Judge	specialties	indexOf("aiml")
Alice	["aiml", "swe"]	0 = best match
Bob	["swe", "aiml"]	1 = secondary match
Carol	["design", "business"]	-1 = no match

IndexOf puts Carol, who is completely unrelated to the front of the queue.

Mostly a non issue for us since every judge will have every track but in case they don't have all of them for whatever reason, it won't result in a bad match.
Edit: Technically possible because you can for some reason delete a specialty for a judge from admin panel

question - what is rowContacts? is that a new row in the devpost csv that is new? Is ProcessedTeamsTable a csv download of success/erorrs?
