feat(mipush): handle missing key by environment mode

Refactor `getMipushKey()` to behave differently across environments:
- In production: fatal on missing key.
- In dev/test: warn and continue with empty key.
- In perf: use mock key.
- Default: fatal for unknown mode.

This prevents non-production environments from crashing when the Mipush key
is not present, while preserving strict validation in production.
