Improvements and fixes

The components and analysis pages can now be filtered by how many of an inverter's strings are verified.

• Components tables now sort by model, serial number, peak power, combiner boxes and strings.
• Sorting the components list by segment or peak power no longer blanks the counts in its Analysis column.
• Opening the add-string dialog on the components page no longer blanks the page.
• A past day opened from a week or month view no longer counts up as though it were today.
• The analysis page's orientation filter is gone, and its station, inverter and combiner-box pickers now sit in their tables' column headers.
