[FLINK-37485][starrocks] Add support for TIME type

[Hisoka-X]

This close https://issues.apache.org/jira/browse/FLINK-37485

This pull request adds comprehensive support for the SQL TIME type (with and without precision) in the StarRocks pipeline connector, including serialization, schema evolution, and documentation updates. It also corrects documentation for timeout parameter types and value ranges, and introduces a new configuration for histogram metric window size.

Pull request overview

Adds end-to-end support for the CDC TIME type in the StarRocks pipeline connector by mapping it to a compatible StarRocks type and validating behavior through unit/integration tests, alongside related documentation and test-stability improvements.

Changes:

• Add TIME schema + serialization handling for StarRocks (mapped to VARCHAR).
• Extend StarRocks connector tests to cover TIME creation, evolution, and serialization.
• Update StarRocks connector docs (option types/ranges, new metric option, TIME mapping) and improve Fluss IT test readiness.
