Restructure navigation: move setup items to Settings with accordion menu

Move rarely-used setup items from main sidebar to Settings to keep
daily-use features prominent:

- Services → Settings > Business section
- Locations → Settings > Business section
- Site Builder → Settings > Branding section

Settings sidebar changes:
- Convert static sections to accordion (one open at a time)
- Auto-expand section based on current URL
- Preserve all permission checks for moved items

Add redirects from old URLs to new locations for backwards compatibility.
