fix(server): use fs-extra default import compat

[hengwuming]

Issue: #75

Reason:

• mrpack deployment could fail under ESM with "fs.readFile is not a function"
• importing fs-extra via is not reliable in this runtime

Changes:

• add a shared fs-extra compatibility wrapper
• switch mrpack and related deployment modules to use the wrapper

Refs: #75
