Expanded user documentation with detailed guidance on average sensors:
1. sensors.md (+182 lines):
- New 'Average Price Sensors' section with mean vs median explanation
- 3 real-world automation examples (heat pump, dishwasher, EV charging)
- Display configuration guide with use-case recommendations
2. configuration.md (+75 lines):
- New 'Average Sensor Display Settings' section
- Comparison table of display modes (mean/median/both)
- Attribute availability details and recorder implications
3. Minor updates to installation.md and versioned docs
Impact: Users can now understand when to use mean vs median and how to
configure display format for their specific automation needs.
