Fixes #3712

Description

TextTarget writes prompts to a local text stream and never contacts a service, but it inherited the default supported_auth_modes of ("api_key",), so New Target described it as "Supported authentication: API key".

• TextTarget declares supported_auth_modes = (), so the registry metadata and /targets/types say it takes no credentials.
• CreateTargetDialog shows "No authentication required" when the registry metadata is loaded and a target reports an empty mode list. The built-in fallback entries (used when the registry is unavailable) also carry [], so they keep showing nothing rather than a claim the dialog can't back.

Tests and Documentation

• tests/unit/registry/test_target_registry.py and tests/unit/backend/test_target_service.py assert the empty list for TextTarget (2 fail on main, pass with the change); the existing api-key-only assertion now uses GitHubCopilotTarget.
• CreateTargetDialog.test.tsx: new test for the "No authentication required" text (fails on main); the target-list test gets the extra TextTarget entry.
• No documentation change; JupyText not run (no notebook touched).

This change was prepared with an AI coding assistant (Claude Code) and submitted by Alex Castillo González.

What changed in this PR

This PR addresses #3712 by identifying TextTarget as credential-free in registry metadata and displaying that information in the target-creation dialog.

Changes:

• Declare that TextTarget supports no authentication modes.
• Show “No authentication required” for empty mode lists from loaded registry metadata, while preserving fallback behavior.
• Add registry, backend, and frontend regression tests.
