Add sample email-agent.claude-project to MCP documentation page

[Copilot]

Adds a ready-to-use Claude project file sample to the MCP admin page so users can connect Claude directly to their mail server without manual configuration research.

Changes

• templates/mcp/page.html — new "Claude Project File" section inserted between the Tools table and the Usage examples, containing the full email-agent.claude-project JSON with:
  • Agent instructions covering safe read-before-act, approval-before-send/delete, and tone-matching behaviours
  • mcpServers block with {{ endpoint_url }} templated dynamically from the server's own MCP endpoint
  • YOUR_PASSWORD placeholder with inline guidance to replace it

{
  "name": "Email Automation Agent",
  "mcpServers": {
    "mailserver": {
      "url": "{{ endpoint_url }}",
      "auth": { "type": "basic", "username": "admin", "password": "YOUR_PASSWORD" }
    }
  }
}
