fix(hana-cloud-ecn): repair malformed tags frontmatter list

[jung-thomas]

Problem

Commit e70c6db ("Updates to the SAP HANA Client tutorials", 2026-09-14) corrupted the tags frontmatter of hana-cloud-ecn:

tags: software-product>sap-hana-cloud, software-product>sap-hana-cloud, software-product-function>sap-hana-cloud--sap-hana-database,tutorial>license]

Missing opening [, a duplicated software-product>sap-hana-cloud (already the primary_tag), and a stray trailing ]. YAML parses this as a string, so the portal parser's tags.map() throws tags.map is not a function, the tutorial is dropped from the build, and the content-rebuild guard fails — the tutorial can no longer be published (prod serves stale content; nightly content-drift check fails).

Fix

Restore the known-good list from the parent commit (60d6705):

tags: [tutorial>intermediate, software-product-function>sap-hana-cloud--sap-hana-database,tutorial>license]

One-line frontmatter fix, no content change.

Detected by the scheduled content-drift check (run 35421247052).
