[core] Generate sidecars for newly written manifests

[leaves12138]

Purpose

Follow up on #9845 and #9886 by generating sidecars for newly created Java manifests. Extracted from #9743 after rebasing that tracking PR onto current master.

• Add manifest.sidecar.enabled, independently overridable and inheriting manifest-sort.enabled when unset.
• Pass table options into the manifest factory and writer. Generate partition coverage for every table, row-ID coverage for data evolution, and bucket coverage when bucket != -1.
• Build from the completed physical manifest after closing its output stream, including rolling writes and raw manifest rewrites.
• Publish _EXTRA_FILES only after the sidecar closes successfully. Writer aborts and sidecar open/write/close failures clean up their own manifest/sidecar pairs, including earlier rolled outputs.
• Keep row-ID statistics unavailable for invalid input ranges.
• Apply the requested blank line after the ManifestIndexTestUtils class declaration.

This PR does not introduce sidecar scan pruning, a read option, Python changes, or a format change. Those remain separate follow-ups.

Validation

Java 8: 309 tests passed; one pre-existing disabled test was skipped. Checkstyle, Spotless and micro-benchmark test compilation passed.

New tests cover unset/default/explicit write switches, no sidecar input I/O when disabled, rolling outputs, raw-copy rewrites, publication after close, abort cleanup, partitioned/unpartitioned tables, independent coverage dimensions, invalid row IDs, and failures during sidecar creation, writing and closing.
