fix: remove incorrect /v1 suffix from OpenRouter API URL (#1749)

The OpenRouter API endpoint should be https://openrouter.ai/api,
not https://openrouter.ai/api/v1. The /v1 suffix was being added
incorrectly, causing API authentication failures.

Fixed in:
- Frontend API provider presets (Profile Edit Dialog)
- Backend Graphiti memory integration config
