FanFolder: alle weergawes en ouer weergawes

What's new in 1.4.3:
- Fixed the taskbar icon showing a colored background plate. The icon is now transparent with no blue card behind it.
- Added altform-unplated assets and built resources.pri so the taskbar renders the icon without plating it with the Windows accent color.
- Scaled the icon to fill the entire tile edge-to-edge and centered it, so it no longer looks smaller than neighboring taskbar icons.

What's new in 1.3.0:
- "Open FanFolder homepage" item on the tray right-click menu (opens the project page in the default browser).
- Anonymous first-run install reporting via Aptabase (EU-hosted, privacy-friendly; opt-out via TelemetryEnabled=0 in HKCU\SOFTWARE\FanFolder; full details in PRIVACY.md). No personal data, file paths, or usage details are sent.

Highlights in 1.2.2:
- Fixed a blank fan window on machines where the configured folder (or the default recent-documents list) is empty: the fan now shows a "This folder is empty" message instead of an empty frame with a loading spinner.
- Removed the unused Microsoft Graph integration and its winhttp / nlohmann_json dependencies, shrinking the build and keeping the app free of runtime network dependencies.
- Documentation fixes: corrected the default animation style, the MaxItems range and the default folder path in the README.
