Adds the input subcommand group for managing JSON payloads used by runs
(create/list/get/update/delete).

- internal/pipelines/input.go: CreateInput, ListInputs, GetInput,
  UpdateInput, DeleteInput — API client for the /inputs endpoints
- cmd/pipelines/input/: input create/list/get/update/delete + inpututil
- docs: input section in pipelines.md, input endpoints in pipelines-reference.md

Inputs exist in draft (mutable) and locked (tied to a version) scopes.
The payload file is wrapped in {"payload": …} before sending to the API.

Apply sunny/pipelines versions of input subcommand files and update
all import paths to use internal/pipeline (singular) after rename.

…ayload DTO, doc fixes

- Add internal/pipeline/input_output_test.go: JSON key remapping (input_id,
  scope/version/pipeline_id), RFC3339 timestamps, empty-list human message,
  table render — mirrors run_output_test.go pattern
- Change inputJSON.Payload from json.RawMessage to map[string]any; remove the
  json.Marshal + ignored-error step in toInputJSON (Payload is already a
  map[string]any from the API decode)
- Fix comment typo: "dr pipelines create" → "dr pipeline create" in
  internal/pipeline/input_payload.go
- Add locked URL variant to input get and input delete rows in
  docs/commands/pipelines-reference.md

…d tests

- Replace Version string (with placeholder) in inputJSON with VersionID *int,omitempty
  so draft inputs omit the field entirely and locked inputs emit a numeric value
- Update input_output_test.go assertions for the new pointer field
- Add input_payload_test.go covering ResolvePayload/resolvePayloadFilePath:
  positional arg, --from-file, both-provided, neither-provided, file-not-found,
  invalid JSON, and non-object JSON
