Replaces the Flask/Alpine web app with a SvelteKit 2 + Svelte 5 rewrite under web/, built on adapter-node and Tailwind v4. Same shape as the reference b4l budget app — no auth, stateless pass-through to InvenTree. New "scan session" flow groups mass scans into a session with live counters (scanned / succeeded / pending / failed). Unknown parts in import mode are fed to a worker pool that spawns inventree-part-import (IMPORT_CONCURRENCY, default 3, with 3-retry). Anything that can't be resolved automatically — parse errors, missing qty, invalid location, API errors, or imports that exhaust retries — drops into a Failures panel with a per-item Fix dialog (edit fields / search existing part / retry import). CSV export on the failure list. Layout is two-column on lg+: scanner + activity on the left, pending imports + failures on the right. Light-theme default. SSE on /api/events streams session and import events to the client. Barcode parser ported from the Python/JS versions and hardened for Digi-Key MH10.8.2 barcodes both with and without GS separators (old parser greedy-matched Q's digits and read "Q6" + "11ZPICK" as 611). Import worker also now treats a subprocess failure followed by a successful findPart as a success, so partial imports (part created but a duplicate parameter trips the DB constraint) no longer land in the Failures panel. Deploy artifacts: systemd unit, nginx example (SSE-friendly), and a step-by-step deploy/README. Requires inventree-part-import >= 1.9.2 on the server for InvenTree 1.x API compatibility.

Feature: Scan Session
- A session groups a run of scans. Every scan goes through
/api/session/scanand is recorded in the session's stats. - Unknown parts in "Add Stock" mode are enqueued for
inventree-part-import; workers run in parallel (tunable viaIMPORT_CONCURRENCY, default 3). - Failures (unknown parts outside import mode, missing qty, invalid location, API errors, and imports that exhaust 3 retries) land in the Failures panel.
- Each failure has a Fix dialog — override the part code / quantity / location, or search for an existing part and link it instead. Retry feeds back through the same code path.
- Export CSV of failures for offline follow-up.
