* Replace FOSS highlight toggle with inline label
Remove the separate "Highlight FOSS" toggle and its theming logic, and instead append an inline "- FOSS" label to FOSS app entries. Changes: remove WPFToggleFOSSHighlight from app navigation and related event handlers, delete FOSSColor resource updates in theme code and button handler, simplify checkbox setup in Invoke-WPFUIElements by removing the special-case toggle logic, and update Initialize-InstallAppEntry to build a horizontal panel containing the app name plus a small green "- FOSS" TextBlock for FOSS items. This consolidates FOSS indication into the item UI and cleans up toggle/theme handling.
* Add inline FOSS label to app entries
Replace the separate StackPanel/TextBlock used for the FOSS indicator with an inline System.Windows.Documents.Run appended to the app name. The run is styled (green RGB(76,175,80) and FontSize=10) and the checkbox content assignment was moved outside the conditional so the appName (with optional FOSS run) is always used. Cleaned up related comments to reflect the FOSS label change.
* Add FOSS note type with green bullet
Added FOSS notes in the UI and FOSS labels with a green bullet instead of the text '#FOSS'
* Use larger circle glyph; remove italic text
Replaced the FOSS and list bullet glyphs with a larger circle for better visual consistency and removed the italic styling
* Update FOSS/bullet glyphs, colors and sizes
Updated FOSS/list bullet styling by switching glyphs from U+2B24 to U+25CF, increasing size (10→11.5), and adjusting bullet/text colors for better visibility and consistency across.
