fix: delete+resend streaming draft instead of edit with HTML parse_mode switch

Browse Source 
Telegram rejects parse_mode changes on existing messages.
Old: editMessageText with HTML on a plain-text message → silent fail, raw ** shown.
New: deleteMessage + sendFormatted (fresh HTML) → always renders bold/italic correctly.
