ThomasandClaude Opus 4.8 42b29f0107 Support separate header logo images for light and dark themes (#36362) ...

Server Pro/CE admins can set a custom header logo via OVERLEAF_HEADER_IMAGE_URL,
but the same image is used for both the light and dark navbar themes. A logo
with good contrast on one background can be hard to see on the other (e.g. a
dark logo on the dark dashboard navbar).

Add two optional env vars, OVERLEAF_HEADER_IMAGE_URL_LIGHT and
OVERLEAF_HEADER_IMAGE_URL_DARK, each falling back to OVERLEAF_HEADER_IMAGE_URL
when unset, so existing configurations are unaffected. The light/dark fallback is
resolved server-side and exposed to the frontend as customLogo (light-effective)
and customLogoDark (dark-effective); the two theme-aware navbars (project
dashboard and library) pick between them using the existing overall-theme hook,
so the logo tracks both the user's theme setting and live OS theme changes.
