The Loyaly mark everywhere a person sees the product

Brand assets in brand/ (the 512px mark, sizes for each surface, a
multi-size .ico). Windows executables carry it as a compiled-in
resource (rsrc_windows_amd64.syso from go-winres) so Explorer, the
taskbar and the installer show it; installer/build.ps1 therefore uses a
plain go build rather than wails build, which would add a second copy
and fail the link. The tray icon is the mark with a state dot over its
corner - a plain coloured circle read as a generic status light among
other icons - rendered from the embedded PNG at 32px so it survives
150% scaling. The desktop app's login, setup and sidebar marks, the
head-office web app's mark and favicon, and the engine dashboard's
favicon are the same file.

Also found while packaging: no wheel so far shipped static/, so the
engine's own dashboard at :8010 on a Windows source install would have
failed with a missing file. package-data now includes it.
