The N8N App Release Telegram Trigger had overwritten the webhook
registration, pointing it to N8N instead of the RSS-News backend.
This caused all callback_query events (inline buttons) to be lost,
breaking the override/rewrite/discard buttons.
Changes:
- Re-register webhook to https://news.vanityontour.de/telegram/webhook
with both message and callback_query in allowed_updates
- Add _forward_to_n8n_app_release() to proxy unknown bot commands
(e.g. /release) to the N8N App Release webhook, keeping that
workflow functional without needing its own Telegram Trigger
