* fix(partition): coerce partition exprs against the batch schema before routing
Batch partition routing (MultiDimPartitionRule::split_record_batch) builds
physical expressions via PartitionExpr::try_as_physical_expr, which did no
type coercion. After widening the time index unit (e.g. ms -> ns via
ALTER TABLE ... MODIFY COLUMN ts TIMESTAMP_NS), the persisted partition
bounds keep their original unit, so evaluating the bounds against the batch
failed with:
Invalid comparison operation: Timestamp(ns) < Timestamp(ms)
Row inserts were unaffected because find_region compares Values and
Timestamp::cmp converts units; scans were unaffected because
PredicateGroup::new coerces the region partition expr against the region
schema first.
Coerce the logical partition expression against the evaluation schema in
try_as_physical_expr before creating the physical expression, the same way
PredicateGroup does. This also covers the region partition filter built for
SST pruning (src/mito2/src/sst/parquet/reader.rs), which shares this
conversion.

* test: regenerate change_col_type result after comment update
The ts_widen_part comment in change_col_type.sql was reworded after the
result file was last generated; sqlness echoes SQL comments into the
result, so the stale comment made the case fail. Regenerate it.
