Ali jawwad 52a6514e38 fix(workflows): reject falsy non-mapping workflow-catalogs.yml top level (#3707)
* fix(workflows): reject falsy non-mapping workflow-catalogs.yml top level

WorkflowCatalog._load_catalog_config parsed the config with
`yaml.safe_load(...) or {}`, then checked `isinstance(data, dict)`. The
`or {}` coerces a FALSY non-mapping top level (`[]`, `false`, `0`, `''`) to
`{}` *before* the guard runs, so those are silently swallowed as "empty
config" and fall back to the built-in defaults -- while a TRUTHY non-mapping
(`5`, a bare list) correctly raises. Same silent-swallow inconsistency the
bundler catalog reader fixed for its own config.

Drop the `or {}` and branch on `None` (empty document / explicit `null`)
explicitly: `None` stays a valid no-op, every non-mapping (falsy or truthy)
now raises the same actionable error. Correct configs are unaffected.

* docs(workflows): describe the catalog-config fallthrough accurately

The comment said a None return means "no project catalogs, fall back to the
built-in defaults". Both halves were imprecise: _load_catalog_config serves the
project AND user configs, and get_active_catalogs falls through env -> project
-> user -> built-in, so a None from the project layer moves on to the USER
config; the built-in defaults apply only once every layer returned None.

Reword the loader comment and the mirror test docstring. Comments only -- no
behaviour change.

* fix(workflows): close the same falsy-mask gap in 'catalogs' and StepCatalog

Self-review follow-up: the top-level fix left the identical asymmetry live five
lines below, and again in this file's twin loader.

1. WorkflowCatalog._load_catalog_config: the ``catalogs`` shape check sat behind
   an emptiness check, so a FALSY non-list (``catalogs: {}``/``''``/``0``/
   ``false``) was silently swallowed as "no catalogs" while ``catalogs: 5``
   raised. Verified before this commit: ``catalogs: {}`` -> None (no error).
   Shape now checked first; absent/explicit-null and empty-list stay no-ops
   (matching the bundler's reader).

2. StepCatalog._load_catalog_config -- the step-catalog twin, read the same way
   -- still had ``yaml.safe_load(...) or {}``, so falsy non-mappings bypassed its
   isinstance guard (``[]`` -> None while ``5`` raised). Same two guards applied,
   keeping the two loaders in lockstep.

Eight new parametrized cases, all failing before this commit.

* test(workflows): move StepCatalog guards into TestStepCatalog and add the nested case

Address three review points:

1. The StepCatalog regression tests sat inside TestWorkflowCatalog, so a
   targeted `pytest ...::TestStepCatalog` run skipped them entirely. Moved into
   that class, where the duplicated twin loader belongs.
2. StepCatalog had no nested-value coverage (only top-level). Added the
   parametrized falsy ``catalogs:`` case, plus the absent/null/empty no-op
   cases. Verified against upstream/main's catalog.py: 8 fail there, pass here.
3. Dropped the inaccurate parity parenthetical. src/specify_cli/catalogs.py
   RAISES for missing/empty ``catalogs`` and coerces a null document to {}, so
   it is not the behavior this loader matches -- the comment now just states
   what changed (only the misreported shapes) without claiming parity.
