fix: Correct LIV Golf border color for invert filter

Calculation: #5e5e5e inverted = #a1a1a1
- Set LIV Golf border to #a1a1a1 in dark theme
- After invert(1) filter → appears as #5e5e5e (correct gray)
- Light theme: resets to normal var(--icon-border)

Filter inverts ENTIRE element including borders, so we
pre-compensate by using the inverse color.
