Fix IcingaDB Web 1.3 compatibility

[brenard]

Following an update to Icinga, specifically IcingaDB Web to version 1.3, I noticed that no information was being displayed in Nagstamon. After investigating, it appears that the IcingaDB Web API now requires all relevant columns to be explicitly requested on getting status.

Additionally, I noticed that while the codebase supports the expire_time field, the UI did not provide a way to input this information. I fixed this and, in doing so, realized that the timezone of the submitted date was not being interpreted correctly by Icinga (resulting in a 1-hour offset in my case). After some research, I found that the icingaweb2-tzo cookie seemed to indicate the client's timezone, so I ensured it was included.

Finally, when running the application from the command line, I encountered annoying MarkupResemblesLocatorWarning warnings, which I suppressed using the recommended method.

Note: I don’t have an IcingaDB Web instance running version 1.2.x to verify compatibility, but since I only added fields to the query, I don’t expect it to cause any issues.

Is an executable for windows x64, that solves this problem available ?

In this version, there is still only one property listed in columns, according to Log anyway ....

@HenriWahl Commit d65a80d seems to be not included in Nagstamon-3.17-20251121. This version still has the same error "KeyError: 'display_name'" because it still asks only for "columns=host.state.last_update" (checked in Debug Log)
I also checked the Source Code Zip from the release "https://github.com/HenriWahl/Nagstamon/archive/refs/tags/latest.zip" and it is missing the changes from commit d65a80d

Apparently the commit was not applied on my branch which I fixed now. A new build is under way: https://github.com/HenriWahl/Nagstamon/actions/runs/19674624592
