fix: billing total display now consistently uses 2 decimals, floor 0.01 for tiny positive amounts\n\n- Previous 6-decimal fallback caused visual inconsistency with list (shows 0.01)\n- Now: raw>0 and toFixed(2)>0 -> normal 2-decimal display\n- Now: raw>0 but toFixed(2)==0 -> floor to 0.01 (minimum visible unit)\n- Matches list column display format, no more '= 0.000125' in detail

fix: prevent float-to-int truncation turning small billing amounts (e.g. 0.01) into 0 in use-price paths\n\n- service/quota.go: replace IntPart() with Round(0).IntPart() + safety net\n- relay/helper/price.go: replace int(float64) with int(math.Round()) + safety net\n- controller/channel-test.go: same fix for test billing calculation\n- All use-price paths now round instead of truncate, and guarantee minimum 1 quota when effective pricing > 0
