Mask a Lakebase oneof member under its group name - #6443

#6443 masks a Lakebase oneof member under its group name, and #6089 adds ./task doctest. The first
lands on rows this catalog was already recording as errors: nine of them, across postgres_projects,
postgres_branches and postgres_endpoints, become OK or SUPPRESSED.

Which is the point of the exercise -- those rows named the bug in the API's own words
("Unknown field path in update_mask") and now name its absence.

## Release v1.15.0

### CLI

 * When `uv python install` fails, `databricks environments setup-local` now falls back to a compatible Python interpreter already installed on the machine. ([#6457](#6457))
 * Allow `databricks environments setup-local` to update `pyproject.toml` files containing TOML multi-line strings. ([#6445](#6445))

### Bundles

 * Before committing the automatic terraform→direct migration, run a deployment plan against the converted state; if the plan fails the migration is abandoned. ([#6486](#6486))
 * The `dbt-sql` bundle template now uses Databricks Runtime 16.4 LTS (up from 15.4 LTS) for classic (non-serverless) compute. ([#6418](#6418))
 * Fixed the direct engine silently ignoring edits to duration and timestamp fields, such as a Lakebase endpoint's `suspend_timeout_duration`. Such a change planned `0 to change` and was never applied. ([#6377](#6377))
 * Fixed `$${...}` not escaping a literal `${...}` on the direct engine, which failed with an `invalid dependency` error. ([#6484](#6484), [#6489](#6489))
 * direct: Fix deploying an update to `postgres_projects.default_endpoint_settings`. ([#6440](#6440))
 * direct: Fix deploying an update to `postgres_endpoints.settings.pg_settings`. ([#6441](#6441))
 * direct: Fix deploying an update to `expire_time`, `ttl` or `suspend_timeout_duration` on Lakebase resources. ([#6443](#6443))
 * Added PyDABs (Python) support for catalogs: `Resources.add_catalog` and the `catalog_mutator` decorator. ([#6408](#6408))
 * Bundle templates now use serverless [environment version 5](https://docs.databricks.com/aws/en/release-notes/serverless/environment-version/five), which offers better performance, and `databricks-connect` 16.4. ([#6378](#6378))
 * Fixed a job with a `table_update` trigger never converging on the direct engine. ([#6442](#6442))

### Dependency Updates

 * Bump Go toolchain to 1.26.8. ([#6476](#6476))

Stacked on #6441 (which is stacked on #6440) — review those first.

Four changes a bundle can express could not be deployed at all:

| resource | field |
|---|---|
| `postgres_branches` | `expire_time`, `ttl` |
| `postgres_endpoints` | `suspend_timeout_duration` |
| `postgres_projects` |
`default_endpoint_settings.suspend_timeout_duration` |

`expire_time` / `ttl` / `no_expiry` are one oneof and
`suspend_timeout_duration` / `no_suspension` another, and the API
accepts them in `update_mask` only under the group name — masking the
field itself is answered with `Unknown field path in update_mask`. All
four now apply and their tests drop `Badness`.

The group names are in neither the OpenAPI spec nor the SDK doc
comments, so each map is hand-written from what the backend accepts,
probed on 2026-08-31. Two members of one group collapse onto a single
mask entry.

`remove_suspend_timeout` still fails, and the mask is no longer why: the
API requires a masked field to be populated in the body, so a removal
has nothing to send. An absent value and an explicit `null` are both
rejected; the supported way to express it is `no_suspension: true`. That
test keeps a `Badness` saying so.
