## Motivation and Context This PR consolidates duplicated list-output formatting across the CLI into shared rendering infrastructure. Currently, each list command has its own copy of the same json/quiet/table branching. This PR pulls that into shared rendering infrastructure in `ContainerCommands`: - `ListDisplayable` protocol for table + quiet output - `renderJSON`, `renderTable`, `renderList` as pure functions that return strings - `emit()` as the single stdout boundary (no-ops on empty strings to avoid blank-line regressions) - `JSONOptions` so all JSON encoding goes through one path, including volume inspect's pretty + ISO 8601 case JSON encoding remains separate from display formatting: each command still chooses its own JSON model, while `ListDisplayable` is used only for table and quiet output. `ImageList` remains the intentional exception for quiet mode so it can avoid unnecessary async work. This change also replaces inline `JSONEncoder` usage with `renderJSON`, removes the old `Codable+JSON.swift` helper, and moves `TableOutput` and `ListFormat` into `ContainerCommands`. It also adds unit tests for the shared rendering helpers and expands integration coverage for image, network, and registry list formatting. ## Testing - [x] Tested locally - [x] Added/updated tests - [ ] Added/updated docs
