Merge b194950c5e into d403044f76

## Rationale 

I have 2 wifi access points with almost identical names, just one has
`_EXT` at the end of it. With the current display limit of 13 characters
before adding ellipsis, I can't tell which is which.

## Summary

Adjusted displayed length from 13 characters to 30 in the Wifi selection
screen - I've left some space for potential proportional font changes in
the future
