add a upload data button in GUI
Add a button to upload test data from GUI.
The button will upload the LATEST test results for the given panel and powerboards selected in the GUI.
There is a message under the button showing the status of the upload. Details of errors etc can be seen from terminal output.
The second small change in this MR is adding a button in the config page to change the institution to the GUI config file. This will be passed to the pbv3_mass_test
program which will be used to save that info to the test result json file and eventually will be used to upload the test result.
