Switch to rebrand themes

[pd-redis]

What

Migrate theme imports from themesDefault to themesRebrand across both theme contexts:

• Update themeContext.tsx to use themesRebrand for the main app
• Update pluginsThemeContext.tsx to use themesRebrand for plugins
• Standardize local variable naming to themes for consistent destructuring pattern

Before	After

Testing

• Visual changes may be present depending on differences between themesDefault and themesRebrand
• Manual verification:
  1. Start the app with yarn dev:desktop
  2. Verify light/dark theme switching works correctly
  3. Check that UI colors and styling match the rebranded theme
  4. Open a plugin (if available) and verify the rebranded theme is applied correctly
  5. Confirm no console errors related to theming

---

Note

Switches theming to the rebranded set and centralizes theme imports.

• Introduces uiSrc/styles/theme to re-export CommonStyles and themesRebrand as themeLight/themeDark, and to host one-time CSS imports
• Updates themeContext.tsx and pluginsThemeContext.tsx to consume CommonStyles, themeLight, and themeDark from the new module; removes direct CSS imports
• Deletes obsolete components/base/theme/index.ts
