feat: Saved Views & Queries (#110)

[mariusmm]

Summary

• Add project-scoped saved views (private/shared) with JSON filter/sort/column definitions, CRUD API, and immutability when locked.
• Wire the requirements SPA to save/apply/update/delete views (including ?saved_view= deep links), plus richer filters, sort, and column visibility with server-side view_id / query params on the requirements list.
• Support baseline from saved view (filtered snapshot + lock view) and apply saved_view on reports requirement loading / CSV via applied table state.

Closes #110

Test plan

• Apply migration 2026-08-04-000001_saved_views (diesel migration run)
• cargo test --features test-helpers saved_view and cargo test --features test-helpers --lib api::baselines::
• cd frontend && npm test -- --run savedView SavedViews
• Manual: save private + shared views; second user sees shared only; reload / deep-link restores filters
• Manual: category/approval/sort/columns persist in a saved view
• Manual: create baseline from a view → snapshot filtered, view locked (edit/delete 409); reports with ?saved_view= scopes requirements
