feat(insights): make the mood distribution and weekday charts more compact and calmer

Both charts derived their height off the full card width via aspect-[3/2],
which ballooned them on a wide viewport and let them dominate the mood
subpage. Bound each to a fixed 150px band so they read as tidy sibling
cards, and align the deferred-load skeletons to the same band.

Soften the saturated full-bleed mood hues to a muted tint (fillOpacity
0.55) so the bars sit calmly over the card while the per-level hue still
distinguishes the bands. On the weekday chart, drop the bright-green 3.5
target guide to a quiet comment-grey dashed line. The shared mood-level
tokens used by the heatmap and legend are untouched.
