fix: preserve add-item drafts after local acceptance failures

[brianorwhatever]

Problem

If adding item A fails before it enters the local queue, AddItemInput restored A into the input even when the user had already typed B. This overwrote the newer draft.

Change

• Preserve the current editable draft on rejection and retain each rejected submission separately for explicit retry.
• Retrying A does not clear or replace B; synchronous guards prevent duplicate immediate submits/retries.
• Remount draft state per account and list, and ignore late feedback/state changes after unmount.
• Explain that these rejected items have not been saved on this device and that the page must remain open to retry them.

This is ephemeral recovery for failures before local queue acceptance, not another server-sync queue. Once onAddItem accepts an item, existing OfflineRecovery owns server retries. Drafts/retry entries are not promised to survive reload or leaving the list/account.

Verification

• Reproduced the original A → type B → reject A overwrite.
• Bun 1.3.5 with the repository test preload: 15 focused tests passed (7 rendered React/Happy DOM/StrictMode tests and 8 handler/source tests).
• Covers rejection, retry with subsequent edits, repeated clicks, repeated failures, list/account remounts, late success/failure, and forwarded input refs.
• Independent review of this exact three-file patch: no blocking findings.
• git diff --check and reverse-patch applicability passed.
• Refreshed main at 8bfcdb7; current open PRs chore(e2e): add e2e runner, example test, and CI workflow #248, Sign action records with owner Turnkey keys through one shared path #277 and fix: make public-list verification labels truthful #289 do not change these files.

Limits

Full repository tests, TypeScript/lint/build, browser E2E, native builds and real IndexedDB integration have not been run locally. Focused tests isolate the local acceptance promise and do not validate the entire offline UX. Automatic CI will be checked on the exact PR head.

Draft only; no merge or deployment.
