From cd66b5bba5fb1c917656097abfee04b381bbbfa6 Mon Sep 17 00:00:00 2001
From: Jan <jan.weber@avatic.de>
Date: Sun, 16 Nov 2025 23:02:11 +0100
Subject: [PATCH] Renamed error store to notification store, centralized
 spinner modal

Increased thread pool capacities in `AsyncConfig.java` and adjusted database schema for larger text fields. Enhanced HS code validation logic and added logging to `EUTaxationApiService` for improved traceability. Cleaned up unused error modal code and aligned styles for calculation processing spinners.
