refactor: replace generic catalog DTOs with shape-typed DTOs for type safety

Replace the single CatalogMaterialDto + CatalogDimensionsDto (bag of nullable
fields) with per-shape DTOs that have strongly-typed dimension properties.
Catalog JSON now groups materials by shape key instead of a flat array.
Delete the old SeedController/SeedDataDtos (superseded by CatalogService).
Scraper updated to emit the new grouped format, resume by default, and
save items incrementally.

+# Alro Steel SmartGrid Scraper — Remaining Steps
+
+## Status: Script is READY TO RUN
+
+The scraper at `scripts/AlroCatalog/scrape_alro.py` is complete and tested. Discovery mode confirmed it works correctly against the live site.
+
+## What's Done
+1. Script written with correct ASP.NET control IDs (discovered via `--discover` mode)
+2. Level 1 (main grid) navigation: working
+3. Level 2 (popup grid) navigation: working
+4. Level 3 (dims panel) scraping: working — uses cascading dropdowns `ddlDimA` → `ddlDimB` → `ddlDimC` → `ddlLength`
+5. Grade filter: 11 common grades (A-36, 1018, 1045, 1144, 12L14, etc.)
+6. Size string normalization: "1-1/2\"" matches O'Neal format
+7. Progress save/resume: working
+8. Discovery mode verified: A-36 Round bars → 27 sizes, 80 items (lengths include "20 FT", "Custom Cut List", "Drop/Remnant" — non-stock entries filtered out in catalog builder)
+
+## Remaining Steps
+
+### Step 1: Run the full scrape
+```bash
+cd C:\Users\aisaacs\Desktop\Projects\CutList
+python scripts/AlroCatalog/scrape_alro.py
+```
+- This scrapes all 3 categories (Bars, Pipe/Tube, Structural) for 11 filtered grades
+- Takes ~30-60 minutes (cascading dropdown selections with 1.5s delay each)
+- Progress saved incrementally to `scripts/AlroCatalog/alro-scrape-progress.json`
+- If interrupted, resume with `python scripts/AlroCatalog/scrape_alro.py --resume`
+- To scrape ALL grades: `python scripts/AlroCatalog/scrape_alro.py --all-grades`
+
+### Step 2: Review output
+- Output: `CutList.Web/Data/SeedData/alro-catalog.json`
+- Verify material counts, shapes, sizes
+- Spot-check dimensions against myalro.com
+- Compare shape coverage to O'Neal catalog
+
+### Step 3: Post-scrape adjustments (if needed)
+
+**Dimension mapping for Structural/Pipe shapes**: The `build_size_and_dims()` function handles all shapes but Structural (Angle, Channel, Beam) and Pipe/Tube shapes haven't been tested live yet. After scraping, check the screenshots in `scripts/AlroCatalog/screenshots/` to verify dimension mapping. The first item of each new shape gets a screenshot + HTML dump.
+
+**Known dimension mapping assumptions:**
+- Angle: DimA = leg size, DimB = thickness → `"leg1 x leg2 x thickness"` (assumes equal legs)
+- Channel: DimA = height, DimB = flange → needs verification
+- IBeam: DimA = depth, DimB = weight/ft → `"W{depth} x {wt}"`
+- SquareTube: DimA = size, DimB = wall
+- RectTube: DimA = width, DimB = height, DimC = wall
+- RoundTube: DimA = OD, DimB = wall
+- Pipe: DimA = NPS, DimB = schedule
+
+**If dimension mapping is wrong for a shape**: Edit the `build_size_and_dims()` function in `scrape_alro.py` and re-run just the catalog builder:
+```python
+python -c "
+import json
+from scripts.AlroCatalog.scrape_alro import build_catalog
+data = json.load(open('scripts/AlroCatalog/alro-scrape-progress.json'))
+catalog = build_catalog(data['items'])
+json.dump(catalog, open('CutList.Web/Data/SeedData/alro-catalog.json', 'w'), indent=2)
+"
+```
+
+### Step 4: Part numbers (optional future enhancement)
+The current scraper captures sizes and lengths but NOT part numbers. To get part numbers, the script would need to:
+1. Select DimA + DimB + Length
+2. Click the "Next >" button (`btnSearch`)
+3. Capture part number from the results panel
+4. Click Back
+
+This adds significant time per item. The catalog works without part numbers — the supplierOfferings have empty partNumber/supplierDescription fields.

+## Grade Filter (editable in script)
+Located at line ~50 in `scrape_alro.py`. Current filter:
+- A-36, 1018 CF, 1018 HR, 1044 HR, 1045 CF, 1045 HR, 1045 TG&P
+- 1144 CF, 1144 HR, 12L14 CF, A311/Stressproof
+
+To add/remove grades, edit the `GRADE_FILTER` set in the script.
