Update multiple dependencies to latest versions

[DeeDee1103]

This pull request updates several package dependencies across multiple projects to newer versions, focusing primarily on upgrading Entity Framework Core and related libraries, as well as test SDKs and telemetry packages. These changes help ensure compatibility with the latest features, security patches, and performance improvements.

Dependency Upgrades

• Upgraded all Microsoft.EntityFrameworkCore packages (including SqlServer, Design, InMemory, and Relational) from version 8.0.12 to 9.0.14 in all service projects and shared infrastructure (StorageLens.Services.*, StorageLens.Shared.Infrastructure, StorageLens.Web). [1] [2] [3] [4] [5]
• Updated Microsoft.Extensions.Http.Polly and Microsoft.Extensions.Caching.StackExchangeRedis to 10.0.5, and Serilog.AspNetCore to 10.0.0 in StorageLens.Shared.Infrastructure.
• Upgraded OpenTelemetry instrumentation and exporter packages to the 1.15.x series, resolving merge conflicts between branches for these dependencies.

Test and Tooling Upgrades

• Updated Microsoft.NET.Test.Sdk to 18.3.0 in all test projects, ensuring compatibility with the latest testing features and bug fixes. [1] [2] [3] [4]
• Upgraded Microsoft.AspNetCore.Mvc.Testing and Microsoft.AspNetCore.TestHost to 8.0.25 in relevant test projects. [1] [2] [3]

These updates collectively modernize the dependency stack, improve maintainability, and help prevent compatibility issues with future .NET releases.

[Copilot]

The project file still contains unresolved Git merge conflict markers (<<<<<<<, =======, >>>>>>>) around the OpenTelemetry package references. This will break restore/build; resolve the conflict and leave a single consistent set of OpenTelemetry package references.

[Copilot]

This project references Microsoft.Extensions.Http.Polly 8.0.12 while StorageLens.Shared.Infrastructure.csproj was bumped to 10.0.5 and is referenced by this project. NuGet will typically resolve to the higher version, so keeping an explicit lower major version here can be misleading and may introduce unexpected breaking API changes at compile/runtime; align the versions (or remove the redundant direct reference if Shared.Infrastructure is intended to control it).

Suggested change

	<PackageReference Include="Microsoft.Extensions.Http.Polly" Version="8.0.12" />
	<PackageReference Include="Microsoft.Extensions.Http.Polly" Version="10.0.5" />

[Copilot]

This project references Microsoft.Extensions.Http.Polly 8.0.12 while StorageLens.Shared.Infrastructure.csproj (which this project references) was bumped to 10.0.5. To avoid version drift and unexpected resolution to a higher major version, align the Polly version across projects or remove the explicit reference here if it should flow transitively from Shared.Infrastructure.

Suggested change

	<PackageReference Include="Microsoft.Extensions.Http.Polly" Version="8.0.12" />
	<PackageReference Include="Microsoft.Extensions.Http.Polly" Version="10.0.5" />
