Support workd_done, remaining_estimate, original_estimate fields via MCP

What is the challenge?

• the Aha MCP tool doesn't expose time tracking fields (work_done,
  remaining_estimate, original_estimate) as writable. They're read-only in the
  detailed view but not in the field schema for updates.

  You'd need to log time through the Aha UI or their REST API directly. The
  MCP integration doesn't support it.

What is the impact?

• Breaking the flow of the users using Aha Develop to switch to UIs

Describe your idea.

• Allow updating the fields
