CLI: catalog listing, auth flags, and OAuth browser UX

[BobDickinson]

Summary

Improve the existing Inspector CLI (mcp-inspector --cli) with catalog introspection, clearer auth controls, and better OAuth UX.

Scope

• servers/list / servers/show against catalog/config (with secret redaction on show)
• --relogin and --stored-auth-only for OAuth flows
• OAuth UX: open the authorization URL in the browser and OSC 8 terminal hyperlinks where supported
• Internal handlers/ extraction in clients/cli (shared structure for method dispatch / formatting)
• Tests and CLI README updates for the above

Acceptance

• Features available via mcp-inspector --cli
• Secrets redacted in servers/show
• CLI README documents the new flags/methods
• npm run ci green
