Bump pyenphase to 1.9.3

[bdraco]

Proposed change

changelog: pyenphase/pyenphase@v1.9.1...v1.9.3

Handle the case where the user has manually specified a password for local auth with firmware < 7.x but its incorrect (or has limited access). If they leave the password blank and chose the username installer we would generate the password for them.

The integration previously accepted any wrong password and would reduce functionality down to what works without a password. We now preserve that behavior to avoid breaking existing installs.

Also handles /production throwing a 401 even with the correct password on some 3.x firmwares.
