Server gui crashing in new release v7.3.1 due to incompatible pydm version

[swh76]

Describe the bug

Server gui comes up, but is blank. Get this error in the server logs:

Also seeing this unrelated warning:

/usr/local/lib/python3.8/dist-packages/pyqtgraph/colors/palette.py:1: RuntimeWarning: PyQtGraph supports Qt version >= 5.15, but 5.12.8 detected.

The latter can be resolved by installing pyqt5 version 5.15 in the server docker before starting the server.

pip install pyqt5==5.15

Running dev version of the server docker, found the problem starts for pydm versions >= 1.19.0. Tested by entering the server dev docker and tried different pydm versions like this;

pip install pydm==1.19.0
/usr/local/src/pysmurf/server_scripts/cmb_eth.py -g -w smurf_scrowaveMuxBpEthGen2_v1.1.1.zip -d /tmp/fw/smurf_cfg/defaults/defaults_c03_lb_lb.yml --enable-em22xx

running on an SO production system. The latest pydm release that works is 1.18.2. It's not obvious to me from the pydm v1.19.0 release notes.

Let's try to fix this by specifying these working versions in https://github.com/slaclab/smurf-rogue-docker/blob/R2.9.0/Dockerfile and bumping the smurf-rogue-docker release to R2.9.1.
