fix(auth): fix device code login crash

Two bugs prevented 'ado login --method device' from working:

  1. The Microsoft identity platform device code API response
     uses 'verification_url' (not 'verification_uri'), causing
     a WithClauseError on the pattern match in request_device_code/1.

  2. CLI.color/2 returns an IO list (not a string), so string
     interpolation in login_device_code/1 raised ArgumentError.
     Fixed by passing the color list directly to CLI.writeln/1
     as an IO list.

Verified locally against the live Microsoft identity platform.
