The Analysis page only showed KPI numbers. Add two real time-series and render
them as dependency-free bar charts (matching components/chat/sparkline.tsx):
- backend: GET /api/analytics now returns `trends.patientsByMonth` (new patients
per month over the last 6 months) and `trends.appointmentsByWeekday`
(appointments per day for the current week), bucketed in JS from one query each.
- frontend: new components/analysis/bar-chart.tsx and two chart sections on the
Analysis view (Patient growth, Appointments this week), with i18n keys.
