PadNav - Controller Suppport

# PadNav 4.8.30

## 🖱️ Controller cursor fixed on every game
- **Fixed: the cursor staying on screen while you play with a controller** (Classic Era). PadNav now keeps the game's controller cursor settings right, automatically: cursor centering off, sticks and jumping put the cursor away, no cursor pop-up for bags. Only wrong settings are changed, chat tells you once, and your own values come back if you set "Cursor pops up for bags" to YES (Cursor tab).

## 🎯 New: Cursor follows the crosshair (Settings > Features)
- When you press **Interact** (usually R3), PadNav puts the game's hidden cursor on your crosshair, so whatever you're looking at shows its name. **PadNav - GatherSpot** uses this to spot fishing pools you look at.
- One move per press, never on its own, never clicks. Skipped while a window is open or on keyboard & mouse.
- Retail hides the cursor right away. On Classic the cursor can't be hidden by add-ons, so PadNav leaves it alone there.

## 🔍 New help commands
- `/pn poolcheck`: what shows up under the crosshair (for fishing pools).
- `/pn cursortest`: whether your game lets PadNav hide the cursor.
