* fix(msteams): read file attachments on Teams channel messages
Three bugs blocked reading files attached to channel messages:
- Graph /teams/{id} used channelData.team.id (the 19:..@thread.tacv2 thread id)
instead of team.aadGroupId (the AAD group GUID) -> 400.
- The Graph fetch was gated on an <attachment id> HTML marker that channel
@mention activities don't carry -> fetch skipped.
- A thread reply was fetched at /messages/{replyId} (404) then fell back to the
bare thread root, returning the root's file for every reply. Replies live at
/messages/{root}/replies/{replyId}.
Fixes#89594
* fix(msteams): gate Graph media fallback on text/html stub; run trigger tests in channel context
* fix(msteams): canonicalize Graph attachment recovery
Build one canonical Graph message URL per Teams activity, recover marker-free channel and group-chat file shares, and retain bounded current-main attachment handling.
