Web: Add SFP state/pin status

Browse Source 
The state of the SFP module is being already send in status.json,
but was not parsed via Web UI. When debuging SFP LOS/Signal detection
it is usefull to see what module is reporting back.

Extended the SFP mouse-over information with:
 - RX LOS as reported in 0x02 bit of register 238
 - External TX Disabled from 0x80 bit of register 238
 - TX fault from 0x04 of the same register
 - The last state of RX LOS pin (available also when there is no 0x40
   option on the module)

This should help identify missing/incorrect setup of TX disabled pin.
