fix: make resource_type optional in ManifestV12 Disabled* classes

dbt manifests (v12) can omit `resource_type` on disabled nodes.
This caused 90 validation errors in production when parsing
docusign's manifest (`run_473557038`), failing `health_check_per_run`.

Made `resource_type` `Optional[...] = None` in all 14 `Disabled*`
variant classes (`Disabled` through `Disabled13`).

Validated against the actual production manifest from S3 —
parses successfully with 3 disabled nodes.
