fix(whatsapp): mark DMs as isMention so router auto-engages

DMs are addressed to the bot by definition. Mirror the chat-sdk-bridge
semantics (onDirectMessage forwards isMention=true) so the host router
can short-circuit DM auto-create + approval flow at router.ts:184
instead of silently dropping inbound from chats it doesn't recognize.

Without this, a v1 → v2 migration where Baileys' LID→phone translation
fails on the first message (no senderPn, signal repository cold) leaves
v2 unable to route DMs at all — the chatJid arrives as `<lid>@lid`,
the migrated messaging_group is keyed by `<phone>@s.whatsapp.net`, and
the router drops because !isMention.

Group messages keep isMention undefined so the router falls through to
agent-name regex matching, unchanged.
