From fd48169219caf56b6a2d509d3cfbe075512bd831 Mon Sep 17 00:00:00 2001
From: jubnl 
Date: Tue, 7 Apr 2026 21:55:41 +0200
Subject: [PATCH 02/11] test(client): expand frontend test suite to 69.1%
 coverage

Add and extend tests across 32 files (+10 595 lines) covering Admin
panels (AuditLog, Backup, DevNotifications, GitHub), Collab (Chat,
Notes, Panel, Polls), Planner (DayDetailPanel, DayPlanSidebar),
Settings (DisplaySettings, Integrations, MapSettings), Files
(FileManager, FilesPage), Map, Layout (DemoBanner,
InAppNotificationBell), shared pickers (CustomDateTimePicker,
CustomTimePicker), Vacay holidays, pages (Dashboard, Login), unit
stores (authStore, inAppNotificationStore), API (authUrl, client
integration), and i18n. Also updates sonar-project.properties and
MSW trip handlers to support the new cases.
