fix(bmp581): add pressure range validation (#26373)

Browse Source 
Reject pressure readings outside the sensor's operating range
(30-125 kPa) to detect I2C data corruption. When I2C transfers
complete successfully but return corrupted data, this check
prevents invalid samples from being published.
