Fix D2R region coordinates and HSV calibration from real screenshot

- Health orb: (370,945)-(460,1030) — verified red center RGB(196,18,16)
- Mana orb: (1580,910)-(1670,1000) — verified blue center HSV(228,94,73)
- Health HSV tightened to H 0-10, S 150+, V 150+
- Mana HSV tightened to H 200-240, S 100+, V 80+
- Belt, skill regions also recalibrated
- 720p regions scaled proportionally
