Function scheduleTokenRefresh

Sets up automatic token refresh before expiry

Schedules a token refresh operation to occur shortly before the access token expires. Dynamically imports the token refresh module to avoid circular dependencies.

This function:

• Calculates the optimal time to refresh (before expiry)
• Sets up a timer to trigger refresh at the right moment
• Ensures only one refresh timer is active at a time
• Logs scheduling information for debugging
• Handles timer creation errors gracefully

// Schedule refresh after receiving new tokens
await scheduleTokenRefresh(3600); // 1 hour token
console.log("Token refresh scheduled for shortly before expiration");
