* fix: use sendDocument for single attachment, sendMediaGroup for 2+

Telegram sendMediaGroup requires 2-10 items minimum. Use sendDocument

* fix: batch sendMediaGroup in groups of 9, add attachments to wasm parser

Telegram sendMediaGroup supports 2-10 items. Batch large attachment
lists into groups of 9. Also add attachments field to commented-out
wasm parser for future compatibility.

* feat: add caption to attachment messages, update wasm patch

Add email sender and subject as caption on Telegram attachment messages.
Caption is shown on the first attachment only for sendMediaGroup.
Update wasm parser patch to include attachments field mapping, and fix
wasm comment to use correct field names (content_type, content as
Uint8Array directly).

* refactor: unify attachment sending with sendMediaGroup for all cases

sendMediaGroup works with 1+ files (tested). Remove sendDocument
special case and always use sendMediaGroup with batching.
