Architecture optimization for AFFiNE cloud

[JasperStardream]

Our team has identified several areas that need to be optimized to improve code stability. We plan to implement the following changes:

### Improve code readability
- [ ] #377 

• [x] toeverything/AFFiNE#1772
• [x] Server-side transaction mechanism: The transaction mechanism will help us avoid data inconsistency and ensure that all requests are processed reliably and consistently.
• [x] toeverything/AFFiNE#1585
• [ ] Ensure the idempotency of API requests: We will ensure that API requests are idempotent, meaning that multiple requests do not have unexpected effects. This will help us avoid data inconsistency and ensure that our system remains stable.
• [ ] Improve system security： Enhance user permissions, and check for issues such as unauthorized access.
• [x] check permissions of blob API

These optimizations will help us create a more stable and efficient system, improving code stability and enhancing the user experience.

Found an issue, the token nonce should not be constant, it's very dangerous to do so.

The issue of API idempotence is mainly related to the following three APIs: /api/workspace POST /api/workspace/:id DELETE /workspace/:id/blob. PUT
