Improvements and fixes

Files of up to 200 MB can now be put into a plant's storage. Each battery container shows its racks, modules and cells, and each of those can be followed with its own curves.

• Files of up to 200 MB can now be uploaded into a plant's storage.
• A file over 50 MB is stored but not analysed automatically and reads "Too large to analyse (over 50 MB)".
• Each battery container now shows how many racks, modules and cells sit below it, and how many of its cells are healthy.
• A converter, rack, module or cell on a battery plant can now be picked and its own curves followed as a graph, heatmap or table.
• A plant's contact list sorts and filters again when it holds entries with no personal name, such as the grid operator.
• A battery component can no longer be marked as verified or given a note, as its details come from the battery system itself.
