Make timezone customized

[PhantomMaa]

Problem:

Currently, Docker images built on Alpine lack the timezone package: tzdata. Upon startup, they can only operate in UTC time and cannot be customized with user-specified timezones.

Solution:

• Install tzdata during image build.
• Default to the Shanghai timezone (TZ=Asia/Shanghai).
• Allow users to customize other timezones via environment variables.
