Normalize tag values during CONTAINS evaluation so that tag-based filtering behaves case-insensitively, consistent with timeseries name filtering.

Hi, I think tag and timeseries name are always both case-sensitive. |

Description
This PR fixes inconsistent behavior of the
CONTAINSoperator when filteringtimeseries by TAGS.
Previously,
SHOW TIMESERIES WHERE TAGS(k) CONTAINS 'value'performedcase-sensitive matching, which differed from the case-insensitive behavior
used for timeseries name filtering. This made tag-based metadata searches
less intuitive and required users to know the exact casing of tag values.
This change normalizes tag values during CONTAINS evaluation, making tag
filtering case-insensitive and consistent with other metadata filters.
