Polish Log Viewer for macOS

Convert detail and filter sheets to shared helpers, add inline Filter /
Export / Clear buttons next to the search bar (toolbar items weren't
surfacing in the settings detail pane), inline the Reset Filters button
at the bottom of the filter sheet, use a 'Close' text button, and trim
the macOS Share Sheet to just the scrollable log with a Copy button.
