fix: guard against undefined resources_string in dashboard list panel

[tbachlechner]

Summary

Fixes #10815 — clicking a log row in a dashboard list panel crashes the frontend.

Root Cause

getFiltersFromResources() in frontend/src/container/LogsExplorerContext/utils.ts calls Object.keys(resources) where resources is log.resources_string. When a log is rendered in a dashboard list panel (not the Logs explorer), resources_string can be undefined, causing:

TypeError: undefined is not an object (evaluating 'Object.keys(e)')

Fix

Add nullish coalescing: Object.keys(resources ?? {}) — returns an empty array when resources_string is undefined, so no filters are created and the log detail view opens normally.

Test plan

• Open a dashboard with a list panel querying logs
• Click on a log row — should open log detail view without crash
• Verify Logs explorer page still works (resources_string is populated there)

Note

Low Risk
Low risk defensive change that prevents a frontend crash when resources_string is missing; behavior when resources are present is unchanged.

Overview
Prevents crashes when opening log details from dashboard list panels by making getFiltersFromResources tolerate an undefined resources_string (treats it as an empty object and returns no resource-derived filters).

Updates the ILog type so resources_string is allowed to be undefined, aligning the type with observed API/UI usage.
