fix(sidebar): align restore indicator with sidebar header and add first-use breathing animation (#990)

- Replace Gruvbox preset with Midnight (deep blue-purple, violet accent)
- Fix accent/info hue collisions in Nord, Monokai, Dracula, Solarized
- Fix Solarized error/warning collision (error-h 25->5) and WCAG contrast
- Make --color-skip-refresh-* follow --color-warning-h dynamically
- Replace hardcoded rgba(24,144,255) in onboarding.css with --color-accent
- Replace hardcoded #00B87A in import modals with --color-success
