Pull request overview

This PR migrates multiple documentation pages from inline C# samples to centralized snippet includes, improving consistency across languages (C#/VB) and making future maintenance of code examples easier.

Changes:

• Replaced inline C# code blocks with {{source=... region=...}} snippet references across Reporting docs.
• Added/paired VB snippet references in several places where only C# was previously shown.
• Normalized some markdown spacing/indentation to align snippet blocks and list formatting.
