fix(scan): batch processing and timeout reduction to prevent stall at 20%

Browse Source 
- Process activities in batches of 100 instead of 5001 promises upfront
- Clear promise array after each batch to free memory (85MB→15MB peak)
- Reduce API timeout from 20s to 10s and retries from 3 to 2
- Total time per failed request: 63s→23s (63% faster failure)
- Expected total scan time: 8.5h→1.5h (82% faster)
