[to dev/1.3] Prevent aligned LAST query from hanging with time filter

[shuwenwei]

Description

Fix aligned multi-measurement LAST queries that may hang when a time filter excludes the only remaining chunk after selected-column pruning.

For aligned series, pruning chunks with no values in the selected measurements can leave a singleton chunk whose statistics differ from the time-series metadata statistics. DiskAlignedChunkMetadataLoader previously skipped time filtering when only one chunk remained, allowing an out-of-range chunk to enter the scan state machine without being consumed.

Changes

• Apply chunk-level time filtering to every non-empty aligned chunk metadata list, including singleton lists.
• Add an integration test covering a multi-measurement LAST query whose selected measurements only exist outside the query time range.

Testing

• Added IoTDBAlignedLastQueryWithTimeFilterIT.
