Visualization table error not captured

[dweindl]

1. Open some valid PEtab problem with visualization table
2. Change yValues to something nonsensical (or introduce some other error)

Expected: An informative error message in the "info" widget

Actual: A not-so-informative error message in the "info" widget:

[2025-09-19 16:06:24] Captured petab lint logs:
    ERROR: Not OK
[2025-09-19 16:06:24] Model is inconsistent.

and the informative part is only visible in the console (if petab_gui was launched from the command line) (e.g., yValues was set to aa, but no such observable exists in the observables table.)
