feat: add configurable logo to login page with light/dark mode support

Browse Source 
- Display Bulwark logo on the login page, with theme-aware switching
  between light and dark variants based on the resolved theme
- Add LOGIN_LOGO_LIGHT_URL and LOGIN_LOGO_DARK_URL env variables to
  allow custom logo overrides (defaults to bundled Bulwark branding)
- Expose logo config through /api/config endpoint and useConfig hook
- Add logo URL prompts to the setup.sh installer branding step
- Rename branding assets to use underscores instead of spaces
