Port and complete #19776 on top of the current Telegram extension layout.
Adds a default-off `channels.telegram.silentErrorReplies` setting. When enabled, Telegram bot replies marked as errors are delivered silently across the regular bot reply flow, native/slash command replies, and fallback sends.
Thanks @auspic7
