Jira issue: CRDB-68184

Start with pkg/sql/catalog/schemaexpr/expr.go at ValidateTTLExpirationExpression and follow the stack into pkg/sql/schemachanger/scbuild/internal/scbuildstmt/alter_table_set_storage_param.go, which handles ALTER TABLE storage parameters. Reproduce the reported ALTER TABLE statement with ttl_expiration_expression set to an invalid value and trace why parsing two statements triggers a panic. Done means the malformed expression is handled without a crash and relevant tests pass; the issue names no specific test.

Written by the indexing model from the issue text.
