Kit articles (multi-component or cantitate_roa≠1) have expected price
differences between GoMag (commercial) and ROA (component sum).
Skip comparison entirely, mark with kit=True flag for UI badge.
Fix kit detection to use float()!=1 (catches cantitate_roa<1 like 0.5).
Update 3 existing tests + add multi-component kit test.

Kit detection only checked cantitate_roa > 1, missing fractional values
like 0.5 (GoMag 50buc/set → ROA 100buc/set). This caused false price
difference alerts (e.g. GoMag 7.00 vs ROA 14.00 for order #481595156).
