Riverlea - disable dark mode by default

[ufundo]

Overview

Lots of CMSes don't like dark mode, so disable it by default in Riverlea. See civicrm/civicrm-buildkit#901

Before

• default is inherit (ie respect your browser/OS's dark mode setting)
• if your CMS theme doesn't support dark mode, then liable to clashes that dont look good

After

• default is light (never use dark mode)
• you can switch it to inherit (or dark) in Display Settings or in Riverlea Settings
