Issue with dashboard screenshot tool

[Airitix]

💬 What Happened?

📋 Bug Description

The "Enable dashboard screenshot mode (beta)" setting has no effect — ha_config_get_dashboard/ha_config_set_dashboard with include_screenshot/return_screenshot always return "Screenshot requested but dashboard screenshot mode is disabled," even with every documented prerequisite satisfied.

🔄 Steps to Reproduce

1. Enable "Enable beta features (master)" in HA-MCP Server Settings.
2. Enable "Enable dashboard screenshot mode (beta)" sub-toggle.
3. Install the Puppet add-on (same repository), set its access_token, confirm it's running.
4. Set "Dashboard screenshot engine URL" to http://<puppet-slug>:10000.
5. Restart the ha-mcp add-on (confirmed full stop/start cycle, not just a state check).
6. Call ha_config_get_dashboard(include_screenshot=True, url_path=..., view_path=...).

✅ Expected vs ❌ Actual Behavior

Expected: A rendered screenshot of the dashboard view, or at minimum an error naming a real remaining blocker (e.g., can't reach Puppet, auth failure).

Actual: Same static message every time: "Screenshot requested but dashboard screenshot mode is disabled. Enable the 'dashboard screenshot' beta feature to use it." — regardless of the above steps.

Did you refresh your tool list on Claude after you enabled the feature? This could just be from a stale tool list.
