feat(s3tables): add compaction strategy to CompactionProperty

[mgarbvs]

Description

Adds compaction strategy support to the S3 Tables L2 construct (@aws-cdk/aws-s3tables-alpha).

The S3 Tables API supports compaction strategies (auto, binpack, sort, z-order) but the CloudFormation L1 spec does not yet include the Strategy property in the Compaction definition. This PR adds L2 support using addPropertyOverride to bridge the gap until the L1 is updated.

Changes

• New CompactionStrategy enum with values: AUTO, BINPACK, SORT, Z_ORDER
• Optional strategy field on CompactionProperty interface
• Uses addPropertyOverride("Compaction.Strategy", ...) since the L1 CFN spec does not yet include Strategy
• 6 new unit tests covering all strategy values and optionality
• Integration test updated with CompactionStrategy.BINPACK
• Snapshot regenerated

Pre-submit checklist

• Lerna build (jsii, eslint, awslint, pkglint): 0 errors
• Rosetta extract: README samples compile
• Unit tests: 218 passed, 8 suites
• Lint: clean
• Integration snapshots: 10/10 UNCHANGED
