Improvements and fixes

Day charts no longer mark false connection loss, strings go to many inverters at once, and a stalled wizard run can be stopped.

• On plants without remote access the day power chart no longer hatches the whole day; its tooltip names affected connections or reports their state unknown.
• The monthly production chart shows a bar slot for every day of the selected range; days without data stay empty instead of being left out.
• Add strings to several inverters or combiner boxes at once; editing a string opens prefilled, and you pick an attachment only where combiner boxes exist.
• In the data logger wizard, "Reconnect" re-establishes a dropped probe stream and keeps your step, credentials and value mapping.
• Anyone who can see a wizard run started by the on-site agent can stop it; an unresponsive run now fails after 30 minutes.
• In the network monitor you pick a device's type from a fixed list, and the device table explains its type icons in a legend.
• The remote-access activity heatmap opens on the most recent weeks, and its weekday labels stay in place while you scroll it.
• On a plant's core data, the image appears in 4:3 with a crop preview, and clicking site or inverter peak power copies it in watts.
