feat: support DCQL wildcard-aware values matching

[lukasjhan]

Summary

• Changed claim values matching to support ClaimPath wildcard elements (allArrayElements)
• Previously used exact ClaimPath dictionary lookup, which failed when the query path contained null wildcards
• Now iterates stored paths and uses contains2 for wildcard-aware matching

Motivation

DCQL queries with null wildcard paths (e.g., ["nationality", null]) could not match against stored credential claim values because the dictionary lookup required exact path
equality.

Changes

• DcqlQueryable.swift: replaced exact dictionary lookup with wildcard-aware path iteration using contains2

Dependencies

• Requires eudi-lib-ios-openid4vp-swift with relaxed MsoMdoc path validation

Hi, I just found out elements of array are not decoded. So we need to implement that as well
