Publish uploaded files

POST /v1/chats/:chatId/files/uploads/publish

Creates one message with previously uploaded files. uploadIds contains IDs from the upload route responses. Repeating after an unknown outcome can create a second message: the client needs its own idempotency ledger.

uploadIds (body) number[] yes 1 to 10 positive IDs
message (body) string no Caption
replyId (body) number no Message ID to reply to
asFile (body) boolean no Send as a file
templateId (body) string no Template ID

Requires the im scope and a write-enabled key. Other fields and query parameters are rejected with 400 INVALID_PARAMS.
