chore(sonar): second sweep — catch .Length, Is.Not.Empty, and newly-exposed Multiple groups (NUnit2046, NUnit2045)

Re-runs `dotnet format analyzers --diagnostics NUnit2046 NUnit2045` after
the Tier 2 Assert.Multiple wrap, which exposed:

- `Has.Length.EqualTo(n)` rewrites for `string[]`/array `.Length` checks
  (the first pass only knew about `.Count`).
- `Is.Not.Empty` rewrites for `Count, Is.GreaterThan(0)`.
- A handful of new NUnit2045 groups that became wrappable once the
  initial Multiple blocks settled the surrounding indentation.

Tests still 1180/1180 passing.
