Issues 19+20: entity-aware schedule import and rollup endpoint

Issue 19:
- entity_id now optional on POST /api/import/schedule
- Resolution: explicit entity_id > name match from row 1 > auto-create
- New params: create_entity_type (default fund), create_vintage_year
- Dry-run reports resolution (will_create/matched/existing)
- Frontend: radio toggle between 'Create from file' and 'Use existing'

Issue 20:
- GET /api/entities/rollup: invested_cents and last_signed_value_cents
  per entity in one pass (SQL aggregates, no waterfall)
- EntitiesList uses rollup instead of N+1 API calls
