refactor(server): decouple services and improve architecture

- Introduce interfaces for all major services (JWT, PostAI, Comment, Message, Notification, QRCodeLogin, Upload, Vote, etc.) to support dependency inversion. - Move query parameters from `internal/dto` to a new `internal/query` package to separate request payloads from data transfer objects. - Refactor `internal/router` to use embedded `RouterDeps` for cleaner dependency management. - Decouple handlers from repositories by injecting services instead of direct repository access, ensuring proper layering. - Improve database initialization by moving it from `internal/model` to `internal/database`. - Optimize message decryption by implementing a more efficient `BatchDecrypt` method in `MessageEncryptor` using a worker pool. - Enhance error handling and security by implementing fail-fast checks for encryption key length during startup. - Clean up unused code, including the `avatar` package and several unused DTOs.
