feat: hackathon stamps page

[jasukej]

Reason

• Allow admins to add, view, and modify stamps for the portal stampbook feature.

Explanation

• CRUD functionality for hackathon stamps.
• Define how stamps should be unlocked by hackers (firebase query vs. qr code) as detailed here + other criteria such as user-facing visibility

Looks amazing, LFG 🚀

Left some comments but only for minor details--should be good to go after! TY 🐐

for isQRUnlockable column, do you think it'd be clearer if the header is just "has QR?" or the cell content is a clear binary value?

I do like the visual variance of the QR icon instead of a boring checkmark, but in the end this is a boolean column so just having a checkmark (similar to criteria and isHidden) might be clearer?

we could use HackathonType here

Suggested change

	export function getHackathonType(hackathonId: string): "cmd-f" | "hackcamp" | "nwhacks" {
	export function getHackathonType(hackathonId: string): HackathonType {

This suggestion positions the criteria badge to be within the popover trigger button, in order to prevent unwanted parent container x-overflow. Only changes 3 lines: lines 137 and the lines surrounding 150 and 163; makes the parent relative positioned and wraps the Badge component to be absolute positioned, right-2 of the parent div.
