feat(telemetry): add workflow_opened with open_source and missing node metrics (#6476)

- Adds app:workflow_opened and plumbs open_source across drag/drop,
file-open button, workspace, and templates
- Tracks missing_node_count and missing_node_types for both
workflow_opened and workflow_imported
- Reuses WorkflowOpenSource type for consistency; no breaking changes to
loadGraphData callers (5th param remains options object; openSource
optional)

Validation
- pnpm lint:fix
- pnpm typecheck

Notes
- Telemetry only runs in cloud builds; OSS remains clean.
- loadGraphData telemetry is centralized where missing_node_types is
computed.
