Subject: [PATCH] Export-DbaCsv, Export-DbaDacPackage - Normalize table/schema
 names via Get-ObjectNameParts

Fixes Group 3 of issue #9010: naive dot-split parsing failed for bracketed dotted table names like [Gross.Table.Name].

- Export-DbaCsv: replace regex ^(.+)\.(.+)$ with Get-ObjectNameParts call
- Export-DbaDacPackage: replace tableItem.Split('.') with Get-ObjectNameParts call

(do Export-DbaCsv, Export-DbaDacPackage)
