### What problem does this PR solve?
Issue Number: None
Related PR: #66950
Problem Summary: Backport #66950 to branch-4.1. Streaming Job converted
every source JDBC column and generated target DDL before checking whether the
mapped Doris target table already existed. An unsupported source type therefore
prevented CREATE JOB even when the user had already created a compatible target
table. This change resolves the mapped target table first and skips
source-to-Doris type conversion only when that target already exists. Source
table identity, primary-key validation, excluded-primary-key validation, and
automatic table creation for missing targets remain unchanged.
### Release note
Allow FROM source TO DATABASE streaming jobs to use precreated target tables
without requiring FE automatic type mapping.
### Check List (For Author)
