[Lake Compute] Read AWS Databricks Unity Catalog tables using Databricks profile PAT/OAuth M2M credentials, declaration-aware validation, and `dbt debug` attach parity. Existing fs `catalogs.yml` entries continue to use `type: unity`. Existing local Unity attach options in `config.lakecompute` must move to `config.duckdb`; Lake Compute access is read-only and Unity model writes are unsupported.
Fix modules.re functions silently dropping keyword arguments (flags=, maxsplit=, count=) (#15508)
Emit only changed columns in Databricks column-tag alter diffs (#16246)
Emit only changed keys in Databricks relation-tag SET TAGS diffs (#16248)

Copy config.group onto the top-level group for source and singular tests, matching dbt-core (#15930)
