Improvements and fixes

Daily energy bars on the analysis page no longer spike on zero counter readings, and you can choose which columns its component tables show.

• The analysis page's daily energy bars and energy totals no longer show spikes when an inverter's, combiner box's or string's energy counter briefly reads zero.
• A negative daily energy bar on the analysis page is set to 0 and offset against the next day.
• On the analysis page, "Select Columns" sets which columns the inverter, combiner box and string tables show.
• The components page's inverter, combiner box and string lists flag a component without data for 1 year.
• A plant's component totals and inverter power count components that were never marked as hidden again.
• The "Report" entry in a plant's menu is greyed out and cannot be opened.
