`PresetCatalog._load_catalog_config` had two "shape check runs after
an emptiness check" bugs, both masking a corrupted preset-catalogs.yml
as an empty/no-op config instead of raising:
- Top level: `yaml.safe_load(...) or {}` coerced a FALSY non-mapping
document (`[]`, `false`, `0`, `''`) to `{}` before the
`isinstance(data, dict)` guard ran, so it was silently treated as
"no config" — while a TRUTHY non-mapping (a bare string) already
raised "expected a mapping at root".
- One level down: `catalogs_data = data.get("catalogs", [])` followed
by `if not catalogs_data: return None` ran the emptiness check
*before* the `isinstance(catalogs_data, list)` check, so a FALSY
non-list `catalogs:` value (`{}`, `''`, `0`, `false`) was silently
swallowed as "no catalogs" — while a TRUTHY non-list
(`catalogs: "not-a-list"`) already raised "must be a list".
`WorkflowCatalog._load_catalog_config` and
`StepCatalog._load_catalog_config` (workflows/catalog.py) already
guard against both cases correctly, with the same explanatory
comments reused here. This preset sibling was missed.

Summary
PresetCatalog._load_catalog_config(src/specify_cli/presets/__init__.py) has two instances of the same "emptiness check runs before the shape check" bug, both of which mask a corruptedpreset-catalogs.ymlas an empty/no-op config instead of raising a clear error:data = yaml.safe_load(config_path.read_text(...)) or {}coerces a FALSY non-mapping document ([],false,0,'') to{}before theisinstance(data, dict)guard runs — silently swallowed as "no config", while a TRUTHY non-mapping (a bare string) correctly raises"expected a mapping at root".catalogs_data = data.get("catalogs", [])followed byif not catalogs_data: return Nonechecks emptiness before checkingisinstance(catalogs_data, list). A FALSY non-listcatalogs:value ({},'',0,false) is silently treated as "no catalogs", while a TRUTHY non-list (catalogs: "not-a-list") correctly raises"must be a list".WorkflowCatalog._load_catalog_configandStepCatalog._load_catalog_config(src/specify_cli/workflows/catalog.py) already guard against exactly both cases, with explanatory comments (# Do NOT coerce with or {} here.../# Same asymmetry ... one nesting level down). This preset sibling wasn't updated to match. Fix reuses the same pattern and comments.Test plan
