fix(tauri): scope About update links by platform

Only include website metadata in the native Linux About dialog, where Tauri renders it as an actionable link. Windows renders the same metadata as inert text and macOS ignores it, so those platforms now rely exclusively on the functional Get Updates menu command.

Cover both supported and unsupported metadata modes and keep the application version available in every native About dialog.

Validated with all 22 Tauri Rust tests, cargo check, git diff checks, and a follow-up gatekeeper review.
