fix: correct Schedule class reference in NotifyReceiver

- Change DatabaseSchema.Schedule to Schedule (same package, no prefix needed)
- Fixes compilation error: Unresolved reference: DatabaseSchema

Since both NotifyReceiver.kt and DatabaseSchema.kt are in the same
package (com.timesafari.dailynotification), Schedule can be referenced
directly without the DatabaseSchema prefix.
