Code review follow-up on acfe29e:
- Switch namespace to Strata.SqlTools.SqlBreakdown.Tests.PostgreSql to
match the dominant convention in the sibling test folder.
- Remove the unreachable SqlServer.CommandVisitor fallback in the
reflection helper. The Assert.That guard alone is enough to surface
a future regression.
