Subject: [PATCH] fix: Remove compiler warnings in Application & Web

- KisApiPriceSource.cs: Use discard pattern for unused exception variables
- Monitoring/Index.cshtml: Handle nullable TotalErrors with null coalescing

Build now passes with 0 code-level warnings (6 remaining NuGet compatibility warnings are harmless).
