Switch sidebar components (FilterSection, FilterSidebar, Pagination)
and both explorer pages to use react-bootstrap: Card, Table, Badge,
Button, Alert, Form.Control, Form.Select, InputGroup, Collapse,
Spinner. Use react-bootstrap-icons for Search, ChevronDown, Download,
BoxArrowUpRight, etc.
Entry detail page: remove MD5 columns from Downloads and Files tables.
Hide empty sections entirely instead of showing placeholder cards.
Human-readable file sizes (KB/MB). Web links shown as compact list
with external-link icons. Notes rendered as badge+text instead of
table rows. Scores and web links moved to sidebar.
No-results alert now shows active machine filter names and offers to
search all machines via Alert.Link.
Update CLAUDE.md with react-bootstrap design conventions and remove
stale ZxdbExplorer.tsx references.
