feat: Add SvelteKit web app with scan sessions and import queue

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.

+# Deployment
+
+Deploy target: Linux server, Node 20+, nginx fronting `adapter-node` on 127.0.0.1:3000, systemd managing the process. Python 3.10+ with `inventree-part-import` installed alongside Node — we shell out to it for unknown parts.
+
+## One-time setup
+
+```bash
+sudo adduser --system --group --home /opt/inventree-stock-tool stock-tool
+sudo chown -R stock-tool:stock-tool /opt/inventree-stock-tool
+
+# As the service user:
+sudo -u stock-tool -H bash
+cd /opt/inventree-stock-tool
+
+# Python side
+python3 -m venv .venv
+source .venv/bin/activate
+pip install "inventree-part-import>=1.9.2"   # 1.9.2+ required for InvenTree 1.x API
+# configure inventree-part-import's suppliers at
+# ~/.config/inventree-part-import/  (Digi-Key, Mouser, LCSC API keys)
+
+# Node side — pushed via git or rsync into /opt/inventree-stock-tool
+npm ci --omit=dev
+npm run build
+
+# Env
+cp .env.example .env
+$EDITOR .env
+```
+
+`.env` must contain at minimum `INVENTREE_HOST`, `INVENTREE_TOKEN`, and
+`INVENTREE_PART_IMPORT_BIN=/opt/inventree-stock-tool/.venv/bin/inventree-part-import`.
+
+## systemd
+
+```bash
+sudo cp deploy/inventree-stock-tool.service /etc/systemd/system/
+sudo systemctl daemon-reload
+sudo systemctl enable --now inventree-stock-tool
+sudo systemctl status inventree-stock-tool
+journalctl -u inventree-stock-tool -f
+```
+
+Adjust `User=`, `Group=`, `WorkingDirectory=` in the unit file to match your
+setup. The unit pins `INVENTREE_PART_IMPORT_BIN` via `.env` — the `PATH=` line
+in the unit is a fallback for when the binary is on a regular `bin` directory.
+
+## nginx
+
+```bash
+sudo cp deploy/nginx.conf.example /etc/nginx/sites-available/stock-tool
+sudo ln -s /etc/nginx/sites-available/stock-tool /etc/nginx/sites-enabled/
+sudo nginx -t && sudo systemctl reload nginx
+```
+
+Then issue a cert:
+
+```bash
+sudo certbot --nginx -d stock-tool.your-domain.example.com
+```
+
+## Updating
+
+```bash
+# on build server / laptop:
+rsync -az --delete --exclude=node_modules --exclude=build \
+  ./web/ stock-tool@host:/opt/inventree-stock-tool/
+
+# on server:
+sudo -u stock-tool -H bash
+cd /opt/inventree-stock-tool
+npm ci --omit=dev
+npm run build
+exit
+sudo systemctl restart inventree-stock-tool
+```
+
+## Tuning
+
+- `IMPORT_CONCURRENCY` (default 3) — number of concurrent `inventree-part-import`
+  subprocesses. Bump up only if supplier APIs aren't rate-limiting you and
+  InvenTree handles concurrent category/manufacturer writes cleanly. 3–4 is
+  typically the sweet spot; higher values tend to produce 429s rather than
+  speedups.
+- `IMPORT_TIMEOUT_SEC` (default 60) — per-attempt timeout. Raise if your
+  supplier API is slow or the server cold-starts imports.
