Publication TOML: add lib/wifi.py

Every source under lib/ and utils/ must appear here; the wifi.py move added a
file and left the manifest behind, failing both the unit test and the reusable
validation workflow:

  AssertionError: Items in the first set but not the second: '/lib/wifi.py'

This is also what puts wifi.py in front of the PyScript gallery, which stopped
getting it from pydevices-examples in the same move.
