Light theme support (app is currently dark-only)

[mericcintosun]

Context. globals.css hardcodes color-scheme: dark and a single dark palette. Some users and reviewers prefer light.

Tasks

• Add a light token set mirroring the existing HSL variables.
• Add a theme toggle (persist in localStorage) and honor prefers-color-scheme.
• Audit hard-coded colors (e.g. Satori OG cards can stay dark).

Files: apps/web/src/app/globals.css, apps/web/src/app/layout.tsx.
Acceptance: the app renders correctly in light and dark, toggle persists.
