…n by reduce partition mapping num (apache#59972) ### What problem does this PR solve? Issue Number: None Related PR: apache#59972 Problem Summary: MV rewrite generated partition mappings and fetched versions for every related-table partition even when the query used only a subset. This backport carries the query-used partition filter through the branch-3.1 single-related-table mapping pipeline, expands RANGE filters to complete MV partition granularity for expression partitions, and fetches versions only for mapped partitions. ### Release note None ### Check List (For Author) - Test: Unit Test - Focused FE unit tests: 24 tests passed - `./build.sh --fe` - Behavior changed: No (performance optimization only) - Does this need documentation: No
