refactor: extract CutTemplate from BomItem for all-item BOM tracking

BomItems are now created for every BOM item regardless of whether they
produce a DXF. Sheet metal cut data (thickness, k-factor, bend radius,
DXF path, content hash) moved to a new CutTemplate entity with a 1:1
optional relationship. Non-sheet-metal items are counted as "skipped"
instead of "failed" in the export summary. Added Cut Templates tab to
the UI with a DataGridView for viewing cut template records.

 # ExportDXF
 
-A Windows desktop application that automates exporting flat pattern DXF files from SolidWorks drawings, assemblies, and parts. Built for sheet metal fabrication workflows, it extracts BOM data, generates DXF flat patterns with etch/bend line markings, exports drawing PDFs, and uploads everything to a CutFab API for downstream cut programming.

 - **Flat pattern generation** with automatic sheet metal detection
 - **Etch line insertion** on bend-up lines for fabrication reference (via EtchBendLines library)
 - **PDF export** of SolidWorks drawings
-- **CutFab API integration** -- uploads DXFs, PDFs, and BOM data with sheet metal properties (thickness, K-factor, bend radius, material)
+- **Local file export** -- saves DXFs and PDFs to a configurable output folder
+- **SQL Server database** -- tracks export history and BOM data via Entity Framework Core
 - **View flip control** with automatic, manual, and prefer-up strategies
-- **Drawing selection UI** that connects to SolidWorks and displays the active document
+- **Active document tracking** -- connects to SolidWorks and displays the active document in the title bar
 - **BOM extraction** from drawing BOM tables or assembly component trees
+- **Drawing history dropdowns** -- equipment and drawing number filters populated from past exports
 
 ## Requirements
 
 - Windows 10/11
-- .NET Framework 4.8
+- .NET 8.0
 - SolidWorks (installed and licensed)
-- CutFab API server (default: `http://localhost:7027`)

+1. **Startup** -- Connects to a running SolidWorks instance (or launches one) asynchronously. Loads past export history from the database to populate equipment/drawing dropdowns. Displays the active SolidWorks document name in the title bar.

    - **Drawing**: Extracts BOM items from BOM tables, exports the drawing as PDF, then iterates through each component to generate flat pattern DXFs.

 3. **Post-processing** -- Each exported DXF is run through the EtchBendLines library, which identifies bend-up lines and adds short etch marks at their endpoints on a dedicated `ETCH` layer. Only up bends are etched because SolidWorks automatically flips the flat pattern so the shortest flange is the first bend. The etch marks let the press brake operator verify part orientation right off the laser table without flipping -- the first bend (shortest flange) will always have an etch line.
 
-4. **Upload** -- DXF files (zipped), PDFs, and BOM item data are uploaded to the CutFab API along with sheet metal properties. The API auto-links cut templates based on material and thickness.
+4. **Save** -- DXF and PDF files are copied to the configured output folder. Export records and BOM items (with sheet metal properties) are saved to the SQL Server database.
