fix(channels): use canonical IMAGE marker in Matrix channel

Matrix image messages used lowercase `[image: ...]` format instead of
the canonical `[IMAGE:...]` marker used by all other channels (Telegram,
Slack, Discord, QQ, LinQ). This caused Matrix image attachments to
bypass the multimodal vision pipeline which looks for `[IMAGE:...]`.

Closes #3486
