DailyRewards

**Changes:

• Improved legacy permission handling.**
  • Legacy rewardslite.use and rewardslite.claim permissions are now disabled by default.
  • They are still supported for backwards compatibility if explicitly granted by the server owner.
  • This prevents legacy permissions from bypassing the new dailyrewards.* permission system.

- Improved admin data safety.

• Admins now receive a clear error message if data.yml cannot be saved.
• This prevents false success messages when a data operation fails.

- Added a new admin data save error message.

- Fixed streak loss notifications.

- Improved streak bonus handling.

- Improved configuration safety.

- Improved cooldown validation.

- Cleaned up the source package.
