fix: use llmopstenant_ gateway prefix and require field settings

- LLMOps endpoints use llmopstenant_ prefix (not llmops_) through
  the platform gateway — llmops_ returns 302, llmopstenant_ routes
  correctly
- SearchField.settings is now required (default FieldSettings()) per
  LLMOps API contract which requires the settings field on each field
- Fixed E2E test feedback endpoint to use llmopstenant_ prefix

E2E results: 5 passed, 1 skipped (ingest skipped because synthetic
trace/span IDs don't exist in LLMOps trace store — needs real agent
trace for full lifecycle test)
