HPDFSignatureProvider

Value	Meaning
`spsValid`	The operation went through
`spsInvalid`	The signature or the input failed verification
`spsUnsupported`	The algorithm, key or capability lies outside the provider's contract
`spsMalformed`	The request input is empty, oversized or structurally unsound
`spsProviderError`	The provider backend failed, say a transport or platform crypto error; remote providers may retry before giving up
`spsCancelled`	The operation was cancelled by way of the provider's cancellation hook

HPDFSignatureProviderStatusName maps every value to a brief display string such as valid, malformed or provider error
Sign and verify helpers fold this status into THPDFSignatureVerifyStatus, surfacing spsProviderError and spsCancelled as svCryptoProviderError
