Ning Sun 5b69770dbc refactor: add field id and extension type to histogram (#8528 )

* refactor: add field id and extension type to histogram

* chore: revert histogram check

* chore: lint

* test: add test coverage for maybe_update_schema

* feat: calculate sub field id from parent column id

* refactor(mito2): guard histogram sub-field ids and cover parquet footer

Address review on #8528:

- native_histogram: derive sub-field ids with checked arithmetic. The SST
  writer now surfaces a new InvalidNativeHistogramSubfield error when a
  sub-field id cannot be resolved (unknown name or i32 overflow) instead of
  silently dropping the id or wrapping. maybe_wrap_schema is now fallible.
- sst: add parquet writer/footer round-trip tests asserting the
  greptime.histogram extension and nested PARQUET:field_id (incl. list
  elements) survive on disk, and a non-canonical struct is left untouched.
- sst: fix a broken rustdoc link to stamp_native_histogram_subfield_ids.
