feat(allowance): add GET and PATCH endpoints for allowance schedules

- GET /guardians/me/allowances: list all children grouped by schedule status
  - withSchedule: children with configured allowances (flattened response)
  - withoutSchedule: children without allowances
  - monthlyTotal: sum of active schedules converted to monthly equivalent

- GET /guardians/me/allowances/summary: lightweight endpoint for home page
  - nextPaymentAt: nearest upcoming payment date
  - monthlyTotal: monthly equivalent total

- PATCH /guardians/me/allowances/:scheduleId: update existing schedule
  - supports partial updates (amount, frequency, status)
  - recalculates nextRunAt when frequency or status changes

- Added interfaces directory for type definitions
- Added response DTOs with flattened junior + schedule data
