💄 Luminare UI updates

[MrKai77]

• Replaces Nucleo icons with SF Symbols for a more native macOS appearance
• Adds colored sidebar icons to more closely match system apps
• Enhances light mode such that section backgrounds are now brighter than their surroundings (inspired by Alcove)
• Buttons now feature a distinct border to improve visibility and clickability
• Keybind search now supports fuzzy matching
• Removes many UI animations for a snappier experience
• Updates string.replacingOccurrences(of:) to string.replacing()
• Improves UI alignment for non-English localizations

That is the only item I can see that will cause issues; the rest looks good. I tested it in light mode (eww) and dark mode. All toggles activate, all switches work, and adding/removing doesn't crash. Everything seems good apart from the small non-included sparkle.
