Add Telegram Topics/Forum Thread support (message_thread_id) #4315
Description
Description
The Telegram notification integration currently only supports sending messages to a Chat ID (channel or group), but does not support Telegram Topics/Forum Threads. This means all notifications are sent to the main chat, which can clutter organized groups that use the Topics feature.
Desired Behavior
Add an optional "Topic/Thread ID" field in the Telegram notification settings (Settings → Notifications → Telegram) that allows users to send notifications to a specific Topic/Forum Thread within a Telegram group.
When configured, Overseerr should include the message_thread_id parameter in Telegram Bot API calls (sendMessage/sendPhoto).
Users can obtain the Topic ID from their Telegram message link: https://t.me/c/CHAT_ID/TOPIC_ID
This would allow users to organize Overseerr notifications into dedicated topics (e.g., "Media Requests", "Plex Notifications") instead of cluttering the main group chat.
