Update plug indicator to show enabled vs total counts

- Change indicator format to show enabled/total for both servers and tools
- Format: 'X (Y servers) A (B tools)' where:
  - X = enabled servers, Y = total servers
  - A = tools from enabled servers, B = total tools from all servers
- Track tool counts per server in localStorage (mcpServerToolCounts)
- Persist tool counts even when servers are disabled
- Examples:
  - No servers: '0 (0 servers) 0 (0 tools)'
  - One disabled server with 2 tools: '0 (1 servers) 0 (2 tools)'
  - One enabled server with 2 tools: '1 (1 servers) 2 (2 tools)'
- Clean up tool counts when servers are deleted
