feat: Code Ocean version 4.1 functionality

[jake-valsamis]

Summary

• Add client.pipelines for pipeline-specific API operations
• Pipelines class uses composition: delegates to an internal Capsules instance with _route="pipelines"
• Only pipeline-named methods are exposed (get_pipeline, search_pipelines, etc.) - no inherited get_capsule etc.
• Capsules now uses configurable _route for API paths (defaults to "capsules")
• Add run_pipeline alias on Computations (same as run_capsule)
• Add endpoint_name and use_input_bucket fields to AWSS3Source
• Add endpoint_name field to AWSS3Target

Test plan

• Verify client.pipelines.get_pipeline() hits /pipelines/{id} endpoint
• Verify client.pipelines.search_pipelines() hits /pipelines/search endpoint
• Verify client.computations.run_pipeline() works same as run_capsule()
• Verify existing client.capsules methods still work unchanged

Pull request overview

This PR adds Code Ocean version 4.1 functionality for pipelines and custom S3 endpoints. It introduces a dedicated Pipelines client that reuses capsule functionality through inheritance, adds support for custom S3 endpoint configuration in data assets, and provides convenient method aliases for pipeline operations.

Changes:

• New pipeline.py module with a Pipelines client class that inherits from Capsules and provides pipeline-specific method aliases
• Added endpoint_name and use_input_bucket fields to S3 source and target configurations in data_asset.py for custom S3 endpoint support
• Added run_pipeline() method alias in computation.py for more intuitive pipeline execution
• Integrated Pipelines client into the main CodeOcean client
• Refactored Capsules class to use a configurable _route attribute, enabling route polymorphism for subclasses
