ui: irl claims requesting & scanning

[govizlora]

• New page /request.html for creating claim requesting entries. Each entry can generate a claim request QR which internally contains:

  {
  claims: string[]
  issuers: string[]
  message: string
  meta: {
  version: string
  }
  }

• In the original login page, a button Scan Request QR is added. It will scan the claim request QR generated by the requester. The requested claim prefixes will be used as the cloak parameter with any auth source to get the token, shown as a QR image.
