fix(ui): stop spurious "failed to read" logo errors in the portable build

Browse Source 
The header and coin logos load disk-first (for dev builds / theme drop-ins) and
fall back to the copies embedded in the exe. The portable single-file build has
no res/img/ folder beside it, so the disk read always failed and logged
"LoadTextureFromFile: failed to read ..." before the (successful) embedded
fallback. Guard each disk load with std::filesystem::exists() so the missing
file is skipped silently and we go straight to the embedded logo — no error
line, logos unchanged.
