Add MCP server component collections to sample/solution

[Dewain27]

Summary

• Adds a new sample/solution/component-collections/ folder with two component-collection exports of the MCP servers used by the demo.
• orderManagementMcp_1_1.zip and warehouseManagementMcp_1_1.zip provide a finer-grained import path than the full EnhancedTaskCompletionDemo.zip for users who only want the MCP connectors.

Notes

This change adds the MCP servers from the sample as standalone component collections, so they can be imported into existing agents without having to install the full demo agents. The full EnhancedTaskCompletionDemo.zip brings the ETC Order Management and ETC Warehouse Management agents along with their connectors and topics, which is more than someone who just wants the MCP connectors needs. With these component-collection zips, a maker can drop only the Order Management MCP and/or Warehouse MCP connector into an agent they already have, instead of importing the entire ETC solution and then carving pieces out of it.

Test plan

• Import component-collections/orderManagementMcp_1_1.zip into a Power Platform environment on the Early Release channel and confirm the Order Management MCP custom connector is created.
• Import component-collections/warehouseManagementMcp_1_1.zip and confirm the Warehouse MCP custom connector is created.
• Create connections for both connectors (no auth required) and verify the tools/list MCP call returns the expected tools.
• Add one of the imported connectors to an existing (non-ETC) Copilot Studio agent and confirm it is usable without importing the full EnhancedTaskCompletionDemo.zip.
