docs: update pinouts and manuals for v1.4.4 universal slot + BME280

- WIRING.md: 16 universal slots (GPIO 0-15) replace fixed DS18B20/DHT22
  assignments. Added BME280 I2C wiring diagram and slot configuration
  section with CLI examples. Updated all three pin reference tables
  to show configurable slots. Added GPIO requirement table per sensor
  type. Updated wiring checklists.
- MANUAL.md: sensor count 11→16, SHT31→DHT22+BME280. Updated pinout
  table with configurable slots. Added Slot Configuration CLI section
  (create, type, pin, name, hwid, active). Added gpio/show sensor types.
  Version bump to v1.4.4-beta.
- README.md: architecture diagram now shows DS18B20×16, DHT22×16,
  BME280×8. Version badge updated.
