fix(insights): localize and auto-send the coach assessment prompt

Thread an autoSend flag through the coach-launch flow so a card's
"ask the coach about this" hand-off dispatches its seeded prompt as
the conversation's first turn instead of only seeding the composer.
The flag rides the launch context, the layout mount, the drawer, and
the shared conversation surface, where a ref-guarded mount effect fires
the send exactly once for a fresh thread.

Localize the previously hardcoded English assessment opener in the
metric status card behind insights.coach.assessmentPrompt with a
{metric} placeholder, and localize the resting-pulse coach prefill.
Both keys land in all six locales.
