`WorkflowCatalog.remove_catalog`, `StepCatalog.add_catalog`, and
`StepCatalog.remove_catalog` all read their config file with
`yaml.safe_load(...) or {}`, which coerces a FALSY non-mapping
top-level document (`[]`, `false`, `0`, `''`) to `{}` before the
`isinstance(data, dict)` check ever runs — silently swallowing a
corrupted config instead of raising, while a truthy non-mapping
(`5`, a bare list with items) correctly raises.
`WorkflowCatalog._load_catalog_config` (used by `get_active_catalogs`)
and `WorkflowCatalog.add_catalog` already guard against this
correctly, with a comment explaining why `or {}` is wrong here; the
other three call sites in the same file reimplement the read inline
and missed the fix. Same shape as the falsy-or-coerce bug class fixed
in github#4094 (preset catalog add/remove) and github#4187 (integration
descriptor loading).

Summary
WorkflowCatalog.remove_catalog,StepCatalog.add_catalog, andStepCatalog.remove_catalog(all insrc/specify_cli/workflows/catalog.py) read their config file withyaml.safe_load(config_path.read_text(...)) or {}.or {}coerces a falsy non-mapping top-level document ([],false,0,'') to{}before theisinstance(data, dict)guard runs, so a corrupted config silently becomes "no catalogs" instead of raising"...corrupted (expected a mapping)". A truthy non-mapping (5, a bare list with items) already raised correctly — this was an inconsistency, and forremove_catalogit surfaces as a misleading"Catalog index N out of range"error instead.WorkflowCatalog._load_catalog_config(the shared loader behindget_active_catalogs) andWorkflowCatalog.add_catalogalready guard against exactly this, with an explanatory comment (# Do NOT coerce with or {} here: ...). The other three call sites in the same file reimplement the read inline and were missed.Test plan
