   ### What problem does this PR solve?
   
   File Scanner V2 applies row-level dictionary-ID filtering to non-string 
Parquet dictionaries. This differs from the V1 and StarRocks strategy, where 
non-string dictionary values are decoded before filtering, and can bypass the 
intended logical value domain.
   
   ### What is changed?
   
   - Restrict row-level dictionary-ID filtering to logical string columns.
   - Keep non-string dictionaries on the decoded-value reader-direct or 
residual VExpr path.
   - Update focused INT/BIGINT/runtime-filter coverage and the V2 Parquet scan 
design.
   
   ### Verification
   
   - ASAN BE UT: 68/68 tests passed for ParquetScanTest and 
ParquetRuntimeFilterDirectReaderTest.
   - clang-format --dry-run --Werror passed.
   - git diff --check passed.
