build: replace Wails3 scaffolding placeholders with NetBird identity

The build/config.yml that wails3 init scaffolded shipped with 'My Company',
'My Product', 'com.mycompany.myproduct' and '(c) 2025, My Company' template
defaults. The per-platform assets generated from it (Info.plist,
Info.dev.plist, info.json, nsis/wails_tools.nsh) carried the same strings,
which were visible in macOS Finder Get Info, Windows .exe Properties and
the NSIS installer.

Updated to the NetBird identity used by the legacy Fyne UI on main:

- companyName / copyright   -> 'NetBird GmbH' (matches main release.yml's
                              COPYRIGHT env passed to goversioninfo)
- productName               -> 'NetBird'
- productIdentifier         -> 'io.netbird.client' (matches CFBundleIdentifier)
- description               -> 'NetBird desktop client'
- darwin NSHumanReadableCopyright   -> 'NetBird GmbH'
- windows LegalCopyright            -> 'NetBird GmbH'
- nsis INFO_COPYRIGHT               -> 'NetBird GmbH'

Version fields (0.0.1) are left in place: release builds get the real
version via goversioninfo (Windows) and sign-pipelines (macOS .app),
so the placeholder is only visible in local task package / task run
output and doesn't reach release artifacts.
