brentperteet 0de59dabfc Add complete manufacturing build pipeline with enhanced features ...

Build Pipeline:
- Generate schematic PDF with all sheets
- Generate 11 individual board layer PDFs (copper, silkscreen, soldermask, paste, fabrication, outline)
- Add "Layer: <name>" text overlay to each board layer PDF
- Merge all board PDFs into single document
- Generate Gerbers with all layers
- Generate drill files in Excellon format
- Generate ODB++ package (optional)
- Export STEP 3D model
- Generate BOMs for active variant
- Package all outputs into timestamped ZIP file
- Real-time progress bar (0-100%) with status updates
- Detailed build log with timestamps
- Auto-download ZIP on completion

Symbol & Footprint Library Integration:
- Browse KiCad symbol libraries from UM_KICAD environment variable
- Live SVG preview of selected symbols with pins, graphics, and labels
- Browse KiCad footprint libraries (.pretty directories)
- Live SVG preview of selected footprints with pads and silkscreen
- Associate symbols and footprints with parts in database
- Store as LibraryName:ComponentName format

WebSocket Connection Improvements:
- Increase ping timeout to 120 seconds (from 60s default)
- Add 25-second ping interval to keep connections alive
- Wait 10 seconds for reconnection before shutdown (handles page refresh)
- Cancel shutdown timer when client reconnects
- Use hidden link download to preserve WebSocket connection (not window.location)

PDF Text Overlay:
- Add reportlab and PyPDF2 imports for PDF manipulation
- Add add_text_overlay_to_pdf() helper function
- Overlay layer names in upper left corner of board PDFs
- Use Helvetica-Bold 14pt font at position (50, 750)

Bug Fixes:
- Fix BOM generator argument order (schematic, project, variant, dnp_uuids, pcb_file)
- Pass empty JSON array '[]' for dnp_uuids instead of output directory
- Move generated BOM files from project dir to output dir for packaging
- Fix datetime import (was missing)
- Use app_args instead of config for getting schematic/board file paths
