## Bug Description

With `store_prompts_in_spend_logs: false` in `general_settings`, embedding responses (full float vectors) are still written to the `response` column in `LiteLLM_SpendLogs`. This causes significant DB bloat — each embedding request stores the complete vector array (e.g. 1024 floats for bge-m3).

## Expected Behavior

With `store_prompts_in_spend_logs: false`, the `response` column should remain `{}` for all call types, including `embedding` and `aembedding`.

## Actual Behavior

The `response` column contains the full embedding response including all float vectors, despite the flag being set to `false`.

## Steps to Reproduce

1. Set `store_prompts_in_spend_logs: false` in `general_settings` 2. Send an embedding request through the proxy 3. Query the DB: ```sql SELECT call_type, length(response::text) FROM "LiteLLM_SpendLogs" WHERE call_type IN ('embedding', 'aembedding') ORDER BY "startTime" DESC LIMIT 5; ``` 4. Observe that `response` contains the full vector data instead of `{}`
