fix(assets): rename Lotus.png so it no longer collides with lotus.png (#229)

public/res/ carried two DIFFERENT files whose names differ only in case —
Lotus.png (19 897 B, the 256px logo used by the welcome page, auth layout,
OIDC config and About) and lotus.png (2 073 B, the notification icon).
Windows and macOS filesystems are case-insensitive, so a checkout there
collapses them into one path: one of the two references then resolves to
the wrong bytes or to nothing, which is why the desktop client's home
logo rendered as alt text from
http://localhost:44548/public/res/Lotus.png.

Renamed the logo to lotus-logo.png and updated its four references;
verified no case-only filename collisions remain anywhere in the repo,
and that both logos still load (256x256 on the welcome page and About).
