Remove 3dfilamentprofiles integration (Issue #7)

3dfilamentprofiles.com has Vercel bot protection blocking automated requests.
Their GitHub repo only has sample data (~3 filaments).
SpoolmanDB already has 6,957+ filaments, making this unnecessary.

Removed:
- spoolman/externaldb.py: ExternalSource enum, Filament3DFP model, 3dfp sync
- client/src/utils/queryExternalDB.ts: ExternalSource enum, source field
- client/src/components/filamentImportModal.tsx: Source filter tabs

-Added 3dfilamentprofiles.com as a second external database source alongside SpoolmanDB.
-
-Backend (`spoolman/externaldb.py`):
-- Added `ExternalSource` enum (SPOOLMANDB, FILAMENT_PROFILES_3D)
-- Added `Filament3DFP` model for raw 3dfp data
-- Added `_transform_3dfp_to_external()` to convert 3dfp format to ExternalFilament
-- Updated `_sync()` to fetch from both sources and merge results
-- Environment variables: `EXTERNAL_DB_3DFP_URL`, `EXTERNAL_DB_3DFP_ENABLED`
-
-Frontend:
-- `client/src/utils/queryExternalDB.ts` - Added `ExternalSource` enum, `source` field, temp range fields
-- `client/src/components/filamentImportModal.tsx` - Added tabs to filter by source (All/SpoolmanDB/3DFP)
-- `client/src/pages/filaments/create.tsx` - Updated import handler for temp range fields
-
-Data mapping (3dfp → Spoolman):
-- `brand_name` → `manufacturer`
-- `color` + `material_type` → `name`
-- `rgb` → `color_hex` (strip # prefix)
-- `properties.temp_min/max` → `extruder_temp/extruder_temp_max`
-- `properties.bed_temp_min/max` → `bed_temp/bed_temp_max`
-- Diameter defaults to 1.75mm (3dfp doesn't provide)
-- Density from material lookup table

 ### Filament Select Not Refreshing After Inline Creation
 When creating a filament via the inline modal on spool create page, the select dropdown doesn't immediately show the new filament with its name (shows ID instead).
 
-### 3dfilamentprofiles Integration Incomplete (Issue #7)
-The backend code and frontend UI exist, but we're only fetching `sample-filaments.json` (~3 test filaments). The jklewa/filament-profiles-data GitHub repo only provides sample data. Full dataset requires either:
-1. Running their parser.py script against 3dfilamentprofiles.com
-2. Directly querying the website API
-3. Hosting our own generated full dataset
+### Issue #7 - 3dfilamentprofiles Integration REMOVED
+The 3dfilamentprofiles.com website has Vercel bot protection that blocks automated requests. Their GitHub repo (jklewa/filament-profiles-data) only provides sample data (~3 filaments). Since SpoolmanDB already has 6,957+ filaments from major brands, the 3dfp integration was removed rather than maintaining dead code.
 
 ### Future: Issue #9 - Hierarchical Locations
 Add room/bin/shelf support for locations. See Gitea issue #9 for details.
