🎉 Version 1.2.0 - Apprise

What's Changed

• [Feature] Add Apprise multi-platform notifications
  This commit introduces Apprise as a new notification provider,
  enabling notifications to over 100 different services like
  Discord, Telegram, and Slack.

  Key changes include:
  - Addition of Apprise notification logic alongside the existing
    SMTP email service.
  - New UI components on the test page to verify Apprise service
    connectivity and to send test notifications.
  - A new setting ('Max characters for Apprise messages') to control
    the length of notification messages, with intelligent truncation.
  - Improved error handling and logging for Apprise API interactions
    to provide clearer feedback on failures.
  - Updated README.md with detailed instructions on how to configure
    the APPRISE_URL environment variable.
