walt-id/waltid-identity — reverse-engineered prompt

Build me an open source digital identity and wallet toolkit like walt.id. I want a simple way to run a full demo locally where someone can issue a digital credential, store it in a web wallet, and then present it to a verifier who can check it.

Please include a white label web wallet for collecting, storing, managing, and sharing credentials and tokens, plus a portal where an organization can issue credentials and verify credentials. Also include local APIs for issuing, verifying, and wallet functions so another app could connect to them later.

Support common identity standards from the docs, like W3C credentials, selective disclosure JWTs, decentralized identifiers, mobile document credentials, and OpenID based credential issuance and presentation. Make it easy to start everything with Docker, and include clear setup instructions, sample data, and a basic happy path demo.

Use Kotlin where it makes sense, and look up current docs online if you need to.
