Add shared normalizeTelegramReplyToMessageId() that rejects non-numeric,
NaN, and mixed-content strings before they reach the Telegram Bot API.
Apply at all four API sinks: direct send, bot delivery, draft stream,
and bot helpers.
Prevents GrammyError 400 when non-numeric values from session metadata
slip through typed boundaries.
Fixes#37222
When a Telegram message that OpenClaw is replying to gets deleted before
delivery, the Telegram API rejects the entire sendMessage call with
"message to be replied not found". This causes the bot's response to be
silently lost and stuck in the failed delivery queue permanently.
Setting allow_sending_without_reply: true tells Telegram to deliver the
message as a standalone message if the reply target no longer exists,
instead of failing the entire request.
Applied to all 6 locations across 4 source files where
reply_to_message_id is set:
- send.ts: buildTelegramReplyParams (both reply_parameters and plain reply)
- bot/delivery.send.ts: buildTelegramSendParams
- draft-stream.ts: draft stream reply params
- bot-handlers.runtime.ts: error reply messages (file too large, media download failed)
