Luke c7af2d4cd3 Deprecate ReducerContext::identity in favor of database_identity (#4843) ...

## Summary
- add `ReducerContext::database_identity()` in Rust bindings
- deprecate `ReducerContext::identity()` and keep it as a compatibility
alias
- update reducer docs example to use `ctx.database_identity()`
- add C# reducer-context equivalent: `DatabaseIdentity` and obsolete
`Identity` alias
- update Rust/C# module test callsites to the new API name
- update C# codegen snapshots for generated `ReducerContext` API output

## Why
Issue #3201 reports user confusion between reducer `ctx.identity()`
(database/module identity) and `ctx.sender`. This change clarifies
naming while preserving compatibility.

## Validation
- `cargo check -p spacetimedb -p module-test` (Passed)
- `dotnet test crates/bindings-csharp/Codegen.Tests/Codegen.Tests.csproj
--nologo` (Passed)
- `dotnet test crates/bindings-csharp/Runtime.Tests/Runtime.Tests.csproj
--nologo` (Failed) pre-existing unrelated failure:
- `Runtime.Tests/JwtClaimsTest.cs(10,23): CS1729: 'JwtClaims' does not
contain a constructor that takes 2 arguments`

## Compatibility
- Rust: `identity()` still works but is deprecated in favor of
`database_identity()`.
- C#: `Identity` still works but is marked `[Obsolete]` in favor of
`DatabaseIdentity`.

Closes #3201
