fix(testmanagement): match bulk path casing "MCP Generated"

Align the createTestCase origin tag with the existing bulk
createTestCasesFromFile path (TCG-utils/helpers.ts), which uses "MCP
Generated" (capital G). Keeps a single canonical tag string across both
create paths for the Test Case Activity Report (PMAA-166).
