Autoconfigure granter validation regex is out of sync with valid policy FQNs

[jakedoublev]

Background

The internal autoconfigure lib contains regex to validate an attribute FQN: https://github.com/opentdf/platform/blob/64798bec1107e379b1a75d2d1b9e14b0fbafb8d3/sdk/internal/autoconfigure/granter.go#L94-L96

https://github.com/opentdf/platform/blob/64798bec1107e379b1a75d2d1b9e14b0fbafb8d3/sdk/internal/autoconfigure/granter.go#L118

This is out of sync with the policy protos for valid namespaces, attributes, and values. Namespace: https://github.com/opentdf/platform/blob/main/service/policy/namespaces/namespaces.proto#L40 Attribute name: https://github.com/opentdf/platform/blob/main/service/policy/attributes/attributes.proto#L55 Value value: https://github.com/opentdf/platform/blob/main/service/policy/attributes/attributes.proto#L132

If the namespace has a hyphen (i.e. https://test-example.com), which is valid from a policy API perspective, creation/encryption of a NanoTDF succeeds, but subsequently fails with service logs:

Given the same namespace, creation/encryption of a ZTDF fails with NewTDFConfig failed: invalid type: attribute regex fail for [https://dsp-demo.com/attr/role/value/guest].
