Improvements and fixes

The day power curve now marks the times a limit held the plant back, and the limits it shows can be chosen.

• The day power curve shades the times the plant ran under a grid or direct marketer limit, with the limit in the tooltip.
• "Show Curtailments" above the curve narrows the shading to grid-operator limits, direct-marketer limits, or none.
• Third-party components received security updates.
