refactor: per-type resources + simplified classification model

Resources renamed from artifactapi_remote to per-type:
- artifactapi_remote_generic
- artifactapi_remote_docker (with ban_tags)
- artifactapi_remote_helm
- artifactapi_remote_pypi
- artifactapi_remote_npm
- artifactapi_remote_rpm
- artifactapi_remote_alpine
- artifactapi_remote_puppet
- artifactapi_remote_terraform (with releases_remote)
- artifactapi_remote_goproxy

Classification simplified:
- patterns: paths to proxy (empty = all, acts as allowlist)
- blocklist: paths to deny (checked first)
- mutable_patterns: override provider auto-classification
- immutable_patterns: override provider auto-classification
- Provider handles mutability automatically per package type
