feat: improve memory service logging and per-assistant configuration

- Enhance memory search logging with structured context in MemoryProcessor
- Add per-assistant memory configuration support in MemoryService
- Reduce log verbosity in StreamProcessingService (debug to silly)
- Fix memory search to use assistant's memoryUserId when available
