Plot more observation vars

[sverhoeven]

Refs #184

To test use test setup from #187 and in vertical plot analyse select

• pressure
• temperature
• relative humidity

Does not add vertical velocity, because I do not know how and do not trust llms to do it correctly.

Pull request overview

This PR adds support for plotting additional observation variables (pressure, temperature, relative humidity) in vertical profile analyses, along with a new feature to load experiments from external URLs.

Key changes:

• Extended observationsForProfile() to support pressure, temperature, and relative humidity variables
• Added URL-based experiment loading via the ?e= query parameter
• Improved toast UX for promise-based operations with persistent error toasts

This also works well. One side note is that if we want to add other variables we might need to extend the interface and schema here:
