Implements a split-panel file browser: directory tree on the left with path input and breadcrumb navigation, file preview on the right with line numbers. Binary/large files (>10MB) show a download prompt instead. Also adds CopyButton component across capsule, snapshot, and template pages, and fixes pre-existing type errors in StatsPanel and admin templates page.
