The visualization UI was still using the old 'hybrid' algorithm name and
weight parameters that were replaced by the BM25 hybrid search refactor.
This caused "Unknown algorithm: hybrid" errors when using the search
& visualize feature.
Changes:
- Update default algorithm from 'hybrid' to 'bm25_hybrid'
- Update default scoreThreshold from 0.7 to 0.0 to match backend
- Remove deprecated semanticWeight, keywordWeight, fuzzyWeight parameters
- Remove weight parameters from search request
Fixes the visualization search functionality after BM25 hybrid refactor.
