CUB-129: fix lint warning in useMemo and add typescript-eslint dev dep

CUB-129: Build Print Jobs list page
- Add PrintJob types (PrintJob, PrintJobFilter) with status union type - Add printJobService.ts using axios + TanStack Query - Build PrintJobsPage.tsx with: - Desktop table: job name, printer, color-coded status badge, started time, duration, filament used, cost - Mobile card layout with grid-based info display - Filter by status (pending/printing/completed/failed) - Filter by printer name - Sort by any column (name, started_at, duration, filament, cost) - Pagination with 20 per page - Loading spinner, error with retry, empty state - Client-side text search by job/printer name - Duration formatting (h/m/s) - Add navigation bar in App.tsx with Inventory + Print Jobs tabs using NavLink

+# Extrudex — Project Context
+
+> **Last updated:** 2026-05-21
+> **Repo:** `CubeCraft-Creations/Extrudex` | **Host:** `code.cubecraftcreations.com`
+> **Local clone:** `/mnt/ai-storage/projects/Extrudex` | **Default branch:** `dev`

+
+## Overview
+
+Custom filament inventory and print tracking system for CubeCraft Creations. Tracks spool consumption, material costs, and per-print COGS across a fleet of 6 FDM printers (5 Bambu Lab + 1 Elegoo Centauri Carbon) + resin printers. Kiosk interface on Raspberry Pi 5 with USB barcode scanner.
+
+**Active refactor in progress:** .NET → Go + React (CUB-110 epic).
+
+## Tech Stack
+
+| Layer | Technology | Notes |
+|-------|-----------|-------|
+| Backend (legacy) | ASP.NET Core 9 + EF Core | Being replaced by Go |
+| Backend (new) | Go 1.24+ | Chi router, pgx (PostgreSQL), gorilla/websocket, paho.mqtt.golang |
+| Frontend (legacy) | Angular 17+ | Being replaced by React |
+| Frontend (new) | React 18 + TypeScript + Tailwind CSS | Vite |
+| Database | PostgreSQL 16+ | snake_case naming |
+| Real-time | SSE (Server-Sent Events) | Replaces SignalR |
+| Printer integrations | Moonraker REST + WebSocket, MQTT TLS | Elegoo/Klipper + Bambu Lab |
+| CI/CD | Gitea Actions | `.gitea/workflows/dev.yml` |
+| Deployment | Docker/Compose, Pi 5 kiosk | |
+
+## Key Design Decisions
+
+1. **Custom system over Spoolman** — Full control over data model and integrations
+2. **MaterialFinish required** on every spool; default is "Basic"
+3. **MaterialModifier is optional**
+4. **Grams derived from:** `mm_extruded × filament_cross_section_area × material_density`
+5. **Push over poll** — SSE + MQTT preferred; Moonraker polling is fallback
+6. **Snake_case** for all PostgreSQL identifiers

+## Known Limitations
+
+- Go rewrite is in progress — backend `internal/` is new Go code, but legacy .NET code still serves endpoints
+- Kiosk deployment not finalized (CUB-114)
+- Smart intake workflow is designed but not implemented
+- MQTT Bambu Lab integration is partially complete (CUB-117)

-# Pi 5 Kiosk Setup — Extrudex (Go + React)
-
-## Prerequisites
-
- Raspberry Pi 5 (4 GB or 8 GB)
- MicroSD card (32 GB minimum, Class 10+)
- HDMI touchscreen display
- USB barcode scanner (HID keyboard mode)
- Power supply (27W USB-C recommended)
-
-## One-Line Setup
-
-```bash
-# 1. Install Raspberry Pi OS (64-bit, Desktop)
-# 2. Enable SSH and VNC
-# 3. Run the automated bootstrap
-curl -sSL https://raw.githubusercontent.com/CubeCraft-Creations/Extrudex/dev/scripts/pi-bootstrap.sh | bash
-```
-
-Or follow the manual steps below.
-
-## Manual Setup
-
-### 1. Install Docker
-
-```bash
-curl -fsSL https://get.docker.com | sh
-sudo usermod -aG docker pi
-```
-
-Log out and back in for group changes to take effect.
-
-### 2. Clone and deploy
-
-```bash
-cd /home/pi
-git clone https://code.cubecraftcreations.com/CubeCraft-Creations/Extrudex.git
-cd Extrudex
-git checkout dev
-
-# Run the deploy script
-chmod +x deploy.sh
-./deploy.sh
-```
-
-### 3. Verify services
-
-```bash
-docker compose -f docker-compose.dev.yml ps
-# All three services should be "Up"
-```
-
-Check the health endpoint:
-```bash
-curl http://localhost:5080/health
-# Expected: {"status":"ok","db_connected":true,"timestamp":"..."}
-```
-
-### 4. Configure kiosk auto-start
-
-```bash
-# Enable the Docker stack service (starts on boot)
-sudo cp systemd/extrudex.service /etc/systemd/system/
-sudo systemctl daemon-reload
-sudo systemctl enable extrudex.service
-
-# Enable the kiosk service (starts Chromium after Docker stack)
-sudo cp systemd/extrudex-kiosk.service /etc/systemd/system/
-sudo systemctl daemon-reload
-sudo systemctl enable extrudex-kiosk.service
-```
-
-### 5. Configure display server
-
-For Pi 5, Raspberry Pi OS uses Wayland by default. If you encounter
-X11-specific issues, switch to X11 in raspi-config (Advanced Options →
-Resolution → X11).
-
-The kiosk service supports both Wayland and X11 display servers.
-
-### 6. Touchscreen calibration (if needed)
-
-```bash
-# Install calibration tools
-sudo apt install -y xinput-calibrator
-
-# Run calibration, note the device ID and parameters
-xinput_calibrator
-```
-
-Add the calibration to `~/.config/labwc/labwc.conf` or `/etc/X11/xorg.conf.d/`
-as appropriate for your display server.
-
-## USB Barcode Scanner
-
-The USB barcode scanner works as a HID keyboard device — it types scanned
-codes followed by an Enter keypress. No driver configuration is needed.
-
-On the React frontend, the search input auto-focuses on page load and
-will capture barcode input immediately. After a touch on another element,
-tap the search field again to re-focus.
-
-## Auto-Refresh on Wake
-
-The React app polls the SSE endpoint every 30 seconds for real-time
-updates. When the Pi wakes from sleep, the next poll will immediately
-sync the UI.
-
-The kiosk service has `Restart=always` and `RestartSec=10`, so Chromium
-will restart within 10 seconds of any crash or power cycle.
-
-## Touch Gestures
-
-Chromium is launched with `--touch-events=enabled` and `--enable-pinch`
-for native touch gesture support:
- **Tap** — click/submit
- **Two-finger scroll** — page scrolling
- **Pinch** — zoom (disabled in kiosk mode by default; enable if needed)
-
-## Troubleshooting
-
-### Services not starting
-```bash
-sudo systemctl status extrudex
-sudo systemctl status extrudex-kiosk
-docker compose -f docker-compose.dev.yml logs
-```
-
-### Kiosk shows blank page
- Ensure Docker stack is running: `docker compose ps`
- Check nginx is serving the React build: `curl http://localhost:5081`
- Check Chromium logs: `journalctl -u extrudex-kiosk -n 50`
-
-### Barcode not working
- Verify scanner is in HID keyboard mode (most USB scanners default to this)
- Open a text field and scan — you should see digits appear
- Check with `dmesg | grep -i usb` for device enumeration
-
-### PostgreSQL connection refused
-```bash
-docker compose -f docker-compose.dev.yml restart extrudex-db
-# Wait 15 seconds, then check health
-curl http://localhost:5080/health
-```
