Subject: [PATCH 1/4] fix: apply dark-mode design tokens to CardModal (#514)

Replace hardcoded bg-white/text-gray-*/border-gray-* Tailwind classes
with surface-container, on-surface, outline-variant, primary, and error
tokens from the Obsidian/Ember design system so the modal respects the
active theme (dark default, light override).

Subject: [PATCH 3/4] fix: apply dark-mode design tokens to FilterPanel (#514)

Replace hardcoded bg-white/border-gray-*/text-gray-* classes with
surface-container-low, on-surface, outline-variant, and primary tokens
from the Obsidian/Ember design system so the filter bar matches the
dark workspace shell.

Subject: [PATCH 4/4] fix(tests): update FilterPanel spec to match dark-mode
 token class rename

Three tests looked up the panel container by `.bg-white` which was
replaced by `bg-surface-container-low` in the #514 dark-mode fix.
Update all three selector strings so the suite stays green.
