- New useReportsPeriod hook reads/writes period via ?from=&to=&period= URL params,
default civil year, pure resolver exported for tests
- New per-domain hooks: useHighlights, useTrends, useCompare, useCategoryZoom
(stubs wired to useReportsPeriod, to be fleshed out in #71-#74)
- Rewire legacy useReports to consume useReportsPeriod; keep backward-compat
state shape (period/customDateFrom/customDateTo) so /reports tabs keep working
- Mark useReports @deprecated pending removal in #76
- Tests: 7 new cases covering resolveReportsPeriod defaults, bookmarks,
invalid inputs, preset resolution
Fixes#70
