In Oracle23aiClient.get(), the limit variable was referenced in log.info() before it was assigned. Python treats limit as a local variable throughout the entire function scope (due to the assignment on the next line), causing UnboundLocalError: cannot access local variable 'limit' where it is not associated with a value when hybrid search calls VECTOR_DB_CLIENT.get(collection_name).
Fix
Move limit = 1000 assignment before the log.info() call so the variable is defined when first referenced.
Impact
Hybrid search with Oracle 23ai was completely broken
Users enabling Hybrid Search and performing RAG queries would hit this crash

### 📄 Description
## Summary
Fixes #22664
## Root Cause
In `Oracle23aiClient.get()`, the `limit` variable was referenced in `log.info()` before it was assigned. Python treats `limit` as a local variable throughout the entire function scope (due to the assignment on the next line), causing `UnboundLocalError: cannot access local variable 'limit' where it is not associated with a value` when hybrid search calls `VECTOR_DB_CLIENT.get(collection_name)`.
## Fix
Move `limit = 1000` assignment before the `log.info()` call so the variable is defined when first referenced.
## Impact
- Hybrid search with Oracle 23ai was completely broken
- Users enabling Hybrid Search and performing RAG queries would hit this crash
- Minimal one-line fix, no behavior change
