[Feature Request] Stream Alarm / Raid Reminder

[DaveMBessler]

Description: Add a "Raid Reminder" feature that alerts streamers 5 minutes before their scheduled stream end to start a raid. This helps ensure they don't forget to raid other channels.

Key Features:

5-Minute Alert: Notifies the streamer 5 minutes before the stream ends.
Customizable: Streamers can enable or disable the reminder from their dashboard.
Notification: Visual and/or audio alert in the streamer's software (e.g., OBS, Twitch chat).
