Problem Summary: Doris initialized Iceberg JDBC Catalog with the Doris local catalog name, which also controls the catalog_name isolation key in Iceberg JDBC metadata tables. This made Doris unable to read metadata written under a different Iceberg JDBC catalog_name, such as Spark's catalog name.
### Release note
Add required iceberg.jdbc.catalog_name for Iceberg JDBC catalog to decouple Doris local catalog name from the Iceberg JDBC metadata catalog_name.
### Check List (For Author)
- Test: Unit Test
- ./run-fe-ut.sh --run org.apache.doris.datasource.property.metastore.IcebergJdbcMetaStorePropertiesTest
- Regression test not run per request; updated test_iceberg_jdbc_catalog to use a custom Doris catalog name with iceberg.jdbc.catalog_name.
- Behavior changed: Yes. Iceberg JDBC catalog now requires iceberg.jdbc.catalog_name and uses it as the SDK catalog name while preserving the Doris local catalog name.
- Does this need documentation: Yes (follow-up docs can describe the new required catalog property).

Iceberg JDBC Catalog uses the SDK catalog initialization name as the `catalog_name` isolation key in JDBC metadata tables, so a Doris catalog named differently from the writer catalog, such as Spark `spark_catalog`, could not list namespaces or tables written under that remote `catalog_name`. This PR adds required `iceberg.jdbc.catalog_name` for Iceberg JDBC catalog and uses it as the Iceberg SDK catalog initialization name. The Doris local catalog name remains independent and continues to be used for Doris namespace/table identifier semantics.

## Description Document the required `iceberg.jdbc.catalog_name` property for Iceberg JDBC Catalog. This updates the current and 4.x Iceberg Catalog docs in both English and Chinese: - Add `jdbc` to the supported `iceberg.catalog.type` values. - Add required `iceberg.jdbc.catalog_name` to the Iceberg JDBC Catalog parameter table. - Explain that it maps to the `catalog_name` isolation key in Iceberg JDBC metadata tables and can differ from the Doris local catalog name. - Update PostgreSQL, MySQL, and SQLite examples to include the property. - Correct `iceberg.jdbc.user` and `iceberg.jdbc.password` from required to optional. - Note that `iceberg.jdbc.driver_class` is required when `iceberg.jdbc.driver_url` is specified.
