Update pages to use pctypeid instead of machinetypeid IN (33-43)

- PCs identified by pctypeid IS NOT NULL instead of machinetypeid list
- Equipment identified by pctypeid IS NULL instead of NOT IN list
- Fixed devicecamera.asp: IDF dropdown uses machinetypeid 17, not 34
- Fixed displaypcs.asp: measuring tool filter uses pctypeid = 7
