deprecate(dds): mark DDS implementation classes as deprecated

[tylerbutler]

Summary

Deprecate DDS implementation classes on the legacy API surface as part of the custom DDS removal effort:

• ConsensusRegisterCollectionClass in @fluidframework/register-collection
• ConsensusOrderedCollection in @fluidframework/ordered-collection
• ConsensusQueueClass in @fluidframework/ordered-collection

These classes expose internal implementation details that consumers should not depend on. Consumers should use the corresponding interfaces (IConsensusRegisterCollection, IConsensusOrderedCollection) for typing and factory/singleton patterns for instance creation.

What changed

• Added @deprecated TSDoc tags to all three implementation classes
• Added eslint-disable comments for import-x/no-deprecated on internal usages (factories and subclasses)
• Regenerated API reports reflecting the @deprecated annotations
• Added changeset

Test plan

• Both packages build successfully (tsc, api-extractor, eslint)
• API reports updated to show @deprecated annotations
