Restyle the Apple Wallet pass after the Check In template

[pradhamk]

Summary

Restyles the Apple Wallet check-in pass (added in #166) to match the "MHacks Check In" Pass Designer template.

• Look: green rgb(56,108,54) background with white text. The template photo is now the pass background, which Wallet blurs. It replaces the sky strip, because Wallet doesn't allow a strip on an event ticket that has a background image.

• Images: the template's white M is now the logo and the thumbnail.

• Front fields: now follow the template:

  • header: Oct 3 / 9:00 AM
  • main field: Date: October 3-4th
  • below it: Name

  The old CCCB / doors / dates row is gone; that information is still on the back of the pass.

• Handbook: the hacker handbook is a viewSchedule featured action, which only appears on iOS 27+. It's also a back field for older devices. The template's URL had a doubled https://https://, which is fixed here.

• Unchanged: the QR code is still the bare user ID, so the scanner doesn't change. Signing and the relevant dates and locations are also untouched.

• Size: the template art is in scripts/wallet-art/, and scripts/generate-wallet-assets.ts resizes it to Apple's sizes. The template's background was 5MB; the whole pass is now about 440KB. When the generator re-ran, the icon and Google Wallet images came out byte-identical.

Deliberately not taken from the template:

• Icon: the template's stadium icon looks like Pass Designer's default, so the MHacks icon stays.
• QR text: the template printed the code as text under the QR. Here that would be a 36-character user ID, so it's left out.
• Google Wallet: the Google pass keeps its current design.

Test plan

• tsc, eslint, prettier
• Built a .pkpass through buildCheckInPass with a self-signed cert. passkit-generator accepts it, and the bundled pass.json and images match the template.
• Open /wallet/pass on an iPhone with the real signing certs and check the front and back.
