fix: compliance report Oracle design, polling robustness, print margins

- Oracle PDF style: decorative left strip, ORACLE brand header, red section titles, green table headers
- Cover page: removed rectangle, clean layout matching Oracle reference PDF
- Print: @page margin:0 + thead/tfoot table trick for per-page header/footer spacing without browser URL/date
- RAG remediation: fixed fallback dumping entire CIS chunk instead of just remediation section
- Findings: removed break-inside:avoid that caused empty pages, emoji replaced with [CSV] text
- Tables: break-inside:avoid on rows, section headers break-after:avoid, thead repeats on page break
- Compliance polling: useEffect-based with cleanup, auto-expand on ready, re-check on section toggle
- Explorer: silent polling during start/stop (no flickering)
- HTML report starts minimized, auto-expands on fresh generation
- Include dist/ in git for deployment
