fix: increase test_case name column size to support long dbt-generated test names

[nikhil255288]

Description

Fixes #25435

Long dbt-generated test names (e.g. accepted_values tests with many arguments)
exceed the current varchar(256) limit on the test_case.name column, causing
ingestion to fail with:
ERROR: value too long for type character varying

Changes

• Increased name column in test_case table from varchar(256) to varchar(2048)
• Added migration scripts for MySQL and PostgreSQL (1.14.0)
• Updated schema files for fresh installs

Type of change

• Bug fix

How was this tested?

Schema change verified against existing migration file patterns in the codebase.

Thanks @nikhil255288 this may create cascading issues. Our recommendation with long dbt name is to use custom names at this point. Closing this for now
