fix: detect+warn garbage product names, add DB cleanup migration 018

- isGarbageName(): detects scraped-slugs, 'All Optical Transceivers', 'Compatible NNGbps...',
  generic form-factor descriptions with no real SKU
- Panel title priority: real standard_name → part_number → description → constructed from specs
- Details warning shown when details_verified = false (amber banner)
- sql/018: marks garbage entries as data_confidence='garbage' for future DELETE
