Wrong download / href URLs at buttons, base_path of server.config.yaml not reflected at URLs

[WickedJack99]

At version change from 0.72 to 0.73 I ran into an issue with the GUI base_path at server.config.yaml .

I'm using:
..
BASE_PATH="/ecto"
..
"GUI": {
"base_path": "'$BASE_PATH'",
..

When trying to download any file from https://172.0.0.1/ecto/... it works but I figured out, that buttons hrefs, which allow to download CSVs are pointing to https://172.0.0.1/... where /ecto is missing.

Here you see I'm accessing the GUI at https://192.168.0.189:8889/ecto/... but the URL for the download has no /ecto in it.
