Four small Insights layout fixes:
- Trends row: render the mood mini chart in the same flat shell the
weight/blood-pressure mini charts use (`bg-card border rounded-md p-2`
with a plain title div) instead of the Card/CardHeader chrome that
stacked extra space above and below the heading. The three trend cards
now share one title baseline and one height.
- Coach settings: place tone and response length side by side (two
columns from `sm`, stacked on mobile) so the sheet no longer needs an
extra scroll length for two short selects.
- Daily briefing: move the heading out of the card into an `<h2>` above
it, matching the heading-above-card pattern the trends and wellness
sections use, so the card opens straight on its content.
- Assessment cards: align the loading skeleton and the mood better-days
card to the canonical `gap-1.5` + `pb-1` heading-to-body rhythm the
populated state already uses, removing the loose ~16-24px gap.
