Extract EventLogExpert.ProviderDatabase library with IProviderDetailsLookup abstraction

[jschick04]

Extracts the provider-database EF Core types from EventLogExpert.Eventing into a new EventLogExpert.ProviderDatabase library, breaking the dependency cycle via an IProviderDetailsLookup abstraction.

Changes

TestUtils scaffolding

• New empty class library projects: Runtime.TestUtils, UI.TestUtils, ProviderDatabase.TestUtils
• Registered in EventLogExpert.slnx under /tests/Shared/

Characterization tests (+18 tests)

• ProviderDatabaseSchemaState boundary tests (NeedsUpgrade for Unknown/v1/v2/v3/Current/Current+1)
• SchemaStateMessages formatting tests
• DatabaseUpgradeException ctor/property tests
• ProviderDetails internal lookup tests (GetEventsById, GetMessagesByShortId with ushort promotion edge case, setter cache invalidation)

ProviderDatabase library extraction

• New EventLogExpert.ProviderDatabase library with EF Core types: ProviderDbContext, CompressedJsonValueConverter, ProviderDetailsMerger, ProviderJsonContext, ProviderJsonSerializerOptions, ProviderDbContextFactory
• Schema DTOs and interfaces remain in Eventing: IProviderDetailsLookup, IProviderDetailsLookupFactory, ProviderDatabaseSchemaState, ProviderDatabaseSchemaVersion, SchemaStateMessages, DatabaseUpgradeException
• IProviderDetailsLookup abstraction decouples EventResolver from concrete ProviderDbContext (no EF Core dependency in Eventing)
• EF Core Sqlite removed from Eventing, replaced with Microsoft.Extensions.Logging.Abstractions
• Namespace renamed from EventLogExpert.Eventing.ProviderDatabase to EventLogExpert.ProviderDatabase for moved files
• All consumer ProjectReferences updated (Runtime, EventDbTool, test projects)
• Factory registered in MauiProgram.cs DI container

Test results

2,193 tests passing (baseline 2,175 + 18 new characterization tests), 0 failures

Pull request overview

This PR extracts the EF Core/SQLite-backed provider database implementation from EventLogExpert.Eventing into a new EventLogExpert.ProviderDatabase library, and introduces an IProviderDetailsLookup/IProviderDetailsLookupFactory abstraction so EventResolver can query provider databases without depending on EF Core.

Changes:

• Introduces EventLogExpert.ProviderDatabase project containing the EF Core ProviderDbContext and related serialization/merge utilities, and wires it into solution/project references.
• Adds IProviderDetailsLookup + IProviderDetailsLookupFactory in Eventing and updates EventResolver to use these abstractions.
• Adds characterization/unit tests for schema state/messages/upgrade exception and provider details lookup behaviors; adds shared *.TestUtils scaffolding projects.

src/EventLogExpert.Filtering/Evaluation/ResolvedEventExtensions.cs:8

• using EventLogExpert.Filtering.Evaluation; is redundant here since the file is already in the EventLogExpert.Filtering.Evaluation namespace, and it can introduce unnecessary-using warnings. Removing it keeps the file cleaner and avoids analyzer noise.
  src/EventLogExpert.Filtering/Evaluation/FilterExtensions.cs:6
• using EventLogExpert.Filtering.Evaluation; is unnecessary in a file that already declares namespace EventLogExpert.Filtering.Evaluation;. Dropping it avoids redundant-usings warnings and keeps the header minimal.
