Subject: [PATCH] fix: make assignedDate and quotaResetDate optional in
 CopilotUsageModels

GitHub's /copilot_internal/user API returns null for assigned_date and
quota_reset_date on trial/free Copilot plans, causing a
DecodingError.valueNotFound when decoding the JSON response.

This change makes both fields optional (String?) to handle null values
gracefully.

Fixes #162
