Add docs for the remaining preview 6 features

[Copilot]

This pull request updates the EF Core 11 documentation with several new features and improvements, especially for SQLite and complex type configuration, along with some minor corrections and enhancements. The most significant changes include new SQLite string aggregation capabilities, support for UInt128, improved configuration of complex types, and wildcard context support in CLI migration commands.

SQLite improvements:

• Added documentation for ordering in string aggregation with string.Join and string.Concat using OrderBy/OrderByDescending in SQLite's group_concat, available in EF Core 11 and requiring SQLite 3.44.0 or later. [1] [2]
• Documented support for binding System.UInt128 parameter values in Microsoft.Data.Sqlite, with correct ordering and comparison in the database.

Complex type configuration:

• Moved and expanded the section on configuring complex type properties via lambda chaining, clarifying that EF Core 11 allows direct property configuration using chained member access in the lambda expression passed to Property. [1] [2]

CLI and tooling enhancements:

• Added documentation for wildcard context (*) support in dotnet ef migration commands, allowing operations across all DbContext types in a project with a single command.

Other documentation corrections:

• Fixed a link to Azure documentation to use a relative path.
• Updated the documentation date.
• Updated a C# language feature link to point to the correct GitHub proposal.
• Updated the Hot Chocolate and Entity Framework Core integration docs link to target the correct version.Addresses several documentation issues: a missing UInt128 limitation callout, a misplaced section, and three broken/absolute links.
