Manual sweep of all 42 IDE0028 sites flagged by SonarQube — `dotnet format
analyzers --diagnostics IDE0028` declined to fix these (no .editorconfig
opt-in for `dotnet_style_prefer_collection_expression`), so applied by
hand. The repo already targets `<LangVersion>latest</LangVersion>` on
net8.0, so C# 12 collection expressions are available.
Pattern: `new List<T>()` / `new Dictionary<K,V>()` / `new ArrayList()` /
`new()` -> `[]` for empty; `new List<T> { ... }` -> `[...]` for literal.
24 files touched in src/{EFCore, LinqToSql, Query, Snowflake, SqlBreakdown,
SqlServer}; tests untouched (no IDE0028 sites in test code).
Build clean (35 warnings unchanged from baseline, 0 errors). All tests
remain green.

The `[Serializable]` attribute and corresponding `[OnDeserialized]` methods have been removed from various breakdown classes. This eliminates reliance on `BinaryFormatter`, which is a deprecated and insecure serialization mechanism in modern .NET.
This change also resolves SonarQube rule S5766 warnings by removing the context in which they apply, leading to cleaner and more secure code.
