fix: expand YAML merge keys in profiles template for dbt-fusion compatibility (#983)

* fix: expand YAML merge keys in profiles template for dbt-fusion compatibility

dbt-fusion's Rust YAML parser does not resolve YAML merge keys (<<:),
causing 'dbt1005: missing type field in resolved profile output' errors
when it tries to parse the 'elementary' profile targets that inherited
fields via merge keys from the 'elementary_tests' anchors.

This commit:
- Replaces the Jinja2 for-loop that generated merge-key-based targets
  in the 'elementary' profile with explicit full target definitions
- Removes the now-unused YAML anchors (&name) from elementary_tests
- Preserves identical rendered output (same fields, same values)

Fixes fusion CI jobs for snowflake, bigquery, and databricks_catalog.

* refactor: use Jinja macros to DRY up profiles while avoiding YAML merge keys
