Fix Settings black-on-black contrast (Gitea #75)
Scope .settings styles to the panel: light #eee text on the dark #121212 surface for labels, and white inputs/selects/options with dark text. Both pairs exceed WCAG 4.5:1. Add settings-contrast e2e as the regression guard for the Settings form plus the sibling dev panels.
