fix(a11y): replace translucent accent washes with authored surfaces

The selected Dashboard summary card rendered lavender, not blue. Its
background was a gradient of statusInfo at 28% and 12% opacity — a
dark-mode trick where a translucent accent over near-black reads as a
dim version of itself. Over a light background the same wash desaturates
toward violet.

Swapped for the authored StatusInfoSurface, which is a real colour with
a real contrast measurement rather than an emergent one. Same treatment
for the selected tag-filter chip (statusInfo at 30%) and an
intelligence-section badge (statusWarning at 14%).

The remaining opacity use, a 0.55 stroke in ContentView, is a border
rather than a text background and is left alone.

Verified across appearance and contrast settings on iOS 18.6: light 21
findings, light + Increase Contrast 18, dark 18, dark + Increase Contrast
18. Increase Contrast lowering the light count is the High Contrast
colorset variants working as intended on the system section headers.
