Pool, competition & round pages overhaul: deep-link context, inline project management, AI filtering UX, email toggle

- Pool page: auto-select program from edition context, URL params for roundId/competitionId deep-linking, unassigned toggle, round badges column
- Competition detail: rich round cards with project counts, dates, jury info, status badges replacing flat list
- Round detail: readiness checklist, embedded assignment dashboard, file requirements in config tab, notifyOnEntry toggle
- ProjectStatesTable: search input, project links, quick-add dialog, pool links with context params
- FilteringDashboard: expandable rows with AI reasoning inline, quick override buttons, search, clickable stats
- Backend: notifyOnEntry in round configJson triggers announcement emails on project assignment via existing email infra
