refactor(avalonia): move global suppressions to source files

Replace assembly-level global suppressions with targeted suppressions at the source level for better maintainability and minimal suppression scope.

- Add RCS1194 suppressions to exception classes using primary constructors
- Add CA2000 suppressions to methods creating HttpContent objects
- Add JSV01 suppressions to LoadProgramResponse and internal JSON wrapper records
- Delete ARMEmulator/GlobalSuppressions.cs
- Keep test global suppressions unchanged
