Changes based on jbtronics' review of PR #1241:
- Rename kicad_export -> eda_visibility (entities, forms, templates,
translations, tests) with nullable bool for system default support
- Merge two database migrations into one (Version20260211000000)
- Rename createCachedJsonResponse -> createCacheableJsonResponse
- Change bool $apiV2 -> int $apiVersion with version validation
- EDA visibility field only shown for part parameters, not other entities
- PopulateKicadCommand: check alternative names of footprints/categories
- PopulateKicadCommand: support external JSON mapping file (--mapping-file)
- Ship default mappings JSON at contrib/kicad-populate/default_mappings.json
- Add system-wide defaultEdaVisibility setting in KiCadEDASettings
- Add KiCad HTTP Library v2 spec link in controller docs
- Add KiCad API v2 endpoints (/kicad-api/v2) with volatile field support
for stock and storage location (shown but not saved to schematic)
- Add kicad_export flag to Orderdetail entity for per-supplier SPN control
(backward compatible: if no flag set, all SPNs exported as before)
- Add EDA completeness indicator column in parts datatable (bolt icon)
- Add ?minimal=true query param for faster category parts loading
- Improve category descriptions (use comment instead of URL when available)
- Improve BOM importer multi-footprint support: merge entries by Part-DB
part ID when linked, tracking footprint variants in comments
- Fix KiCost manf/manf# fields always present (not conditional on orderdetails)
- Fix duplicate getEdaInfo() call in shouldPartBeVisible
- Consolidate supplier SPN and KiCost field generation into single loop
Replace manual If-None-Match comparison with Response::setEtag() and
Response::isNotModified(), which properly handles ETag quoting, weak
vs strong comparison, and 304 response cleanup. Fixes PHPStan return
type error and CI test failures.
- Use empty Response instead of JsonResponse(null) for 304 Not Modified
to avoid sending "null" as response body
- Guard parse_url() result with is_string() since it can return false
for malformed URLs
- Move storage location tracking inside the availability check so
expired and unknown-quantity lots don't contribute locations
- Add Stock field showing total available quantity across all part lots
- Add Storage Location field when parts have stored locations
- Resolve actual datasheet PDF from attachments (by type name, attachment
name, or first PDF) instead of always linking to Part-DB page
- Keep Part-DB page URL as separate "Part-DB URL" field
- Add ETag and Cache-Control headers to all KiCad API endpoints
- Support conditional requests (If-None-Match) returning 304
- Categories/part lists cached 5 min, part details cached 1 min
