feat(services): add fetch_price_info_range service and update schema

Added new service for fetching historical/future price data:
- fetch_price_info_range: Query prices for arbitrary date ranges
- Supports start_time and end_time parameters
- Returns structured price data via service response
- Uses interval pool for efficient data retrieval

Service definition:
- services.yaml: Added fetch_price_info_range with date selectors
- services/__init__.py: Implemented handler with validation
- Response format: {"priceInfo": [...], "currency": "..."}

Schema updates:
- config_flow_handlers/schemas.py: Convert days slider to IntSelector
  (was NumberSelector with float, caused "2.0 Tage" display issue)

Impact: Users can fetch price data for custom date ranges programmatically.
Config flow displays clean integer values for day offsets.
