Function getTokenExpiry

getTokenExpiry(): null | number
Gets the token expiry timestamp

Delegates to the token-operations module's getTokenExpiry function, preserving the same function signature for backward compatibility.

Returns null | number
Timestamp when the token expires (milliseconds since epoch) or null
Example
```
// Check token expiration
import { getTokenExpiry } from "./auth/storage/token-store";

const expiry = getTokenExpiry();
if (expiry) {
  const minutesRemaining = Math.floor((expiry - Date.now()) / 60000);
  console.log(`Token expires in ${minutesRemaining} minutes`);
}
```
Deprecated
Use getTokenExpiry from token-operations directly
Source
```
export function getTokenExpiry(): number | null {
  return getTokenExpiryOp();
}
```
