fix(windows): show app version on About screen + capitalize Punktfunk on licenses

The About settings card had no version at all — add an identity block (app name +
"Version <CARGO_PKG_VERSION>", the workspace version) at the top, the WinUI
Settings convention and matching the Apple client's "Version X" wording. Also
capitalize the brand name on the licenses screen (was lowercase "punktfunk").

Verified against the pinned windows-reactor source + cargo fmt --check; full
Windows link left to CI (Windows-only crate).
