The parser validates unsupported schemas and supports nanosecond conversion. Tests cover parser behavior, real-TiKV imports, float32 writing, and conflict resolution.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: ⚪ Minimal · up to Parquet imports now preserve nanosecond temporal values and unsigned UINT_32 values using logical-type metadata.

Full details: Out of Scope Changes checkExplanation The core changes match the linked issues, but adding float32 support in parquet_writer.go is not connected to the TIME(NANOS), TIMESTAMP(NANOS), or UINT_32 objectives. The shard-count change also needs justification as test infrastructure for this PR. ✨ Finishing Touches🧪 Generate unit tests (beta)

- Around line 58-59: Resolve the cherry-pick conflict in the mydump Parquet
implementation by removing all conflict markers and retaining the logical-type
handling and timestamp-nanos expectations. Ensure both files consistently use
the package-local ParquetFileMeta, ParquetColumn, WriteParquetFile, and
NewParquetParser symbols, with the parser remaining in the mydump package and no
references to a dumpformat/parquetfile parser.

Run make bazel_prepare and commit the generated Bazel metadata.

What problem does this PR solve?
Issue Number: close #70368, close #70359
Problem Summary:
TIME(NANOS)andTIMESTAMP(NANOS)are valid Parquet LogicalTypes, but they have no legacy ConvertedType counterpart. TiDB's import path previously reduced LogicalType metadata to ConvertedType and could interpret nanosecond values as ordinary integers. UINT_32 values above 2^31 were also sign-extended when decoded from physical INT32 values.What changed and how does it work?
