Refactor configuration data export and template loading functions

- Updated Export-ConfigurationData to use resolved configuration data directly and added error handling for missing data.
- Enhanced Load-Templates to streamline category loading and improve error handling for missing template directories.
- Removed Merge-ConfigurationData function as it is no longer needed.
- Refactored Merge-Templates to improve merging logic and handle default files more effectively.
- Introduced Get-TemplatePreviewData function to handle template preview data retrieval and merging.
- Added Import-OrderedPowerShellDataFile function to support ordered hashtable imports.
- Updated Update-ParametersPanel to handle parameter and variable tab updates more efficiently.
- Improved Update-TreeView to handle cases where resources are not found.
- Added new parameters to Environment.Default.psd1 for Active Directory configuration.
- Created new template BGW-LAN.psd1 for domain configuration.
