Markdown support for status pages and MCP updates

Added

• Add support for markdown on the AppSignal status pages. You can now use markdown in the main description, and status updates.

  

• Add get_triggers MCP Tool. This tool exposes all the anomaly detection triggers and is in preparation for the create/update trigger tool.
• Add get_app_resources MCP Tool. This tool exposes multiple application resources such as users, namespaces, and dashboards. It will be the home of application resources that do not need any additional filtering.

• Remove get_namespaces MCP tool in favor of get_app_resources.
