fix(cmc/formSpec): rename FORM_SPEC_EVENT_TYPE to hds-form-spec/v1 (slash separator)

Pryv's events.get `types` filter rejects values that don't match
`^(series:)?[a-z0-9-]+/(\*|[a-z0-9-]+)$` with
`invalid-parameters-format`. The previous value `'hds:form-spec-v1'`
(colon separator) silently passed events.create but failed every
events.get + loadFormSpec call.

Never observed before because no consumer of saveFormSpec / loadFormSpec
existed in production — discovered when plan 61 C1.a (FormBuilder write
port) made these the first live callers. No data migration needed.

Updates `[CFS01]` + `[CFS40]` assertions. 546/546 tests pass.
