This PR fixes TikTok attachment send failures and adds a capability-based guard so attachments are only enabled for conversations that support media sending. - Fixed TikTok media upload request formatting so TikTok accepts image uploads reliably. - Added TikTok capability check (IMAGE_SEND) during conversation creation. - Stored capability in conversation.additional_attributes.tiktok_capabilities. - Updated reply composer UI to disable/hide attachment upload for TikTok conversations where image_send is false.
