Fully Integrate API Notifications with Slack Bot

[Rich-T-kid]

Description
Complete the Slack bot's integration with the API to handle various events and send notifications. These events should include:

• API stats exceeding a threshold.
• Multiple consecutive errors from the API.
• Server start and stop events.
• Server crashes.

Tasks

• Enhance the Slack bot to handle additional events (e.g., errors, server lifecycle events).
• Add logic to group and notify for consecutive errors.
• Send notifications for server start and stop events.
• Implement crash detection and notifications.
• Update documentation to include all supported notifications and how to configure them.

Acceptance Criteria

• The bot sends notifications for all specified events.
• Consecutive errors trigger a grouped notification.
• Server lifecycle events (start, stop, crash) are correctly detected and notified.
