[style](ui): make Guide, Chat Advisor, Guide me cards fully opaque (owner request)

All three floating/modal cards (Guide/Panduan, Chat Advisor, Guide me/Pandu Saya)
now use solid backgrounds instead of the semi-transparent glass effect. Overrides
the .aa-glass transparency with background: var(--color-background-primary).
