feat(04-01): multi-project schema migration — projects, settings, FK pivot
- schema.ts: add projects table, settings kv table, slug on clients;
migrate 6 FK from client_id to project_id (phases, payments, documents, notes,
time_entries, quote_items); update all relations and TypeScript types
- admin-queries.ts: fix getAllClientsWithPayments + getClientFullDetail to aggregate
through projects; add getAllProjectsWithPayments, getProjectFullDetail,
getClientWithProjects, ClientWithProjects type
- settings.ts: new file — getSetting, updateSetting, getTargetHourlyRate, SETTINGS_KEYS
- Fix all downstream files: actions.ts, quote-actions.ts, new/actions.ts,
timer-actions.ts, approve/route.ts, comment/route.ts, TimerCell.tsx,
analytics-queries.ts, client-view.ts, seed.ts
- DB migration applied to Coolify Postgres (all test data cleared, schema rebuilt)
