fix(models): add missing creation_time initialization in Zone class and fix incorrect type (str -> int) (#1891)

## Summary
- Add missing `creation_time` parameter to `Zone.__init__()`
- Fix timestamp type annotations from `str` to `int` to match API format

## Problem
The `Zone` class declared `creation_time` as an attribute but never
initialized it in `__init__`, causing `AttributeError` when accessed.

## Test plan
- [x] All existing tests pass
- [x] Pre-commit checks pass
