feat: add file monitoring guidelines to settings with provider-specific instructions

Add a new "File Monitoring Guidelines" section in plugin settings that displays provider-specific information about uploaded file retention and cleanup. The section includes a help button that opens the Plugin Guide modal and updates dynamically based on the selected AI provider (Claude, Gemini, or OpenAI). Also update help modal content with file monitoring information and fix example template link.

+##### File Monitoring
+
+When you upload files (PDFs, images) to conversations, they are stored by your AI provider. The plugin automatically attempts to delete these files when you delete conversations, but this may occasionally fail due to network issues or API rate limits.
+
+**What to do:**
+- Periodically check your provider's dashboard for uploaded files
+- Remove any old files that are no longer needed
+- Provider-specific details can be found in the plugin settings
+
+**Provider Dashboards:**
+- Claude: [Anthropic Console](https://console.anthropic.com/)
+- Gemini: [Google AI Studio](https://aistudio.google.com/)
+- OpenAI: [OpenAI Platform](https://platform.openai.com/)`,
