fix: Make from_memory_type and to_memory_type optional and add task_id propagation

- Make from_memory_type and to_memory_type fields optional in ScheduleLogForWebItem
- This fixes RabbitMQ log submission validation errors in cloud service scenario
- Add task_id field to ScheduleMessageItem and ScheduleLogForWebItem
- Propagate task_id from API request through scheduler to web logs
- Add logging for preference memory additions in _pref_add_message_consumer

Fixes validation error:
'2 validation errors for ScheduleLogForWebItem
from_memory_type Field required
to_memory_type Field required'

Changes:
- src/memos/mem_scheduler/schemas/message_schemas.py: Add task_id fields
- src/memos/multi_mem_cube/single_cube.py: Pass task_id to ScheduleMessageItem
- src/memos/mem_scheduler/general_scheduler.py: Propagate task_id to logs
