test: Fix and enhance MCP Claude headless flow smoke test

This commit resolves path resolution issues and correctly initializes
the MCP environment for testing the headless discovery pipeline.

Changes:
- Corrected REPO_ROOT calculation to accurately locate script artifacts.
- Implemented automatic MCP initialization via Admin interface:
    * Enabled MCP (mcp-enabled=true).
    * Disabled SSL (mcp-use_ssl=false) to avoid handshake issues in CI.
    * Registered a valid MCP target profile (mysql-127.0.0.1-13306).
    * Registered an authentication profile (default_mysql).
    * Properly loaded MCP variables and profiles into runtime.
- Updated static_harvest.sh invocation to use the unencrypted HTTP
  endpoint.
- Added extensive diagnostic logging to show exact command execution
  and intermediate results (Run IDs).
- Verified the end-to-end dry-run orchestration of the discovery
  pipeline.
