Pull request overview

This PR adds a new view-credential CLI command that displays verifiable credentials in a human-readable format. The command complements the existing get-credential command, which outputs raw JSON, by providing formatted output with field labels and proof verification.

Changes:

• Adds view-credential <did> command that decrypts and displays credentials with formatted labels for type, issuer, subject, validity dates, schema, claims, and proof status
• Updates help reference documentation and test expectations to include the new command
• Implements the command in both JavaScript (archon-cli.js) and TypeScript (cli.ts) versions with consistent behavior
