fix(#7325): guard env casts against malformed input

[Yzgaming005]

Summary

Module-level int(os.getenv(...)) / float(os.getenv(...)) in tools/webhooks/webhook_server.py crashes on import if the env var contains malformed (non-numeric) input.

Fix

Wrapped casts with _safe_int / _safe_float helpers — return the default value instead of crashing.

Testing

Before: malformed env var → ValueError on import.
After: gracefully falls back to default.

Closes #7325
