/**
 * Generates the TqFormFileInput wrapper — the in-form upload field behind
 * `<tq-form-file-input>`. It is a pure controlled input over a page state
 * whose value is an ARRAY of PickedFile POJOs
 * `{ name, size, type, lastModified, dataURL }` — the exact shape the
 * `browser-pick-files` workflow node emits and `file-storage-upload`
 * consumes (dataURL→Blob). Nothing is uploaded at pick time: the
 * form-submit workflow reads the state via state-get-local-state and
 * uploads there. Commits go through the page-supplied `onChange`
 * (`event.target.value` = JSON) and are mirrored into a paired hidden
 * input (no `name`, so it never leaks into form payloads) that dispatches
 * a native `change` for the platform's element-trigger machinery — the
 * same bridge the signature widget uses.
 *
 * Bug 6 (encode race): `readAsDataURL` is async, so a form-submit workflow's
 * synchronous "is state.<key> empty?" gate — evaluated the instant Submit is
 * clicked — used to read the OLD (empty) state if the user clicked Submit
 * before a large file's encode resolved. `handlePick` now commits an
 * IMMEDIATE placeholder entry (same shape, `dataURL: ''`) synchronously, in
 * the SAME native `change` event as the pick, so `.length` reflects "a file
 * is selected" before any later, separate click could possibly fire. The
 * placeholder is replaced with the fully-encoded entry once the async read
 * resolves (or rolled back to the pre-pick selection if every read fails).
