feat: Customize pfQuest addon to make it easier for first-time users

## Overview
Modified pfQuest addon to skip the initial setup window and reposition the GPS navigation arrow for improved user experience.

## Files Changed

### config.lua
- **Setup Window Disabled**: Changed `if pfQuest_config.welcome ~= "1" then` to `if false then` in the pfQuestInit OnEvent script
- **Effect**: The welcome/setup window will never appear, allowing the addon to use default configuration values automatically
- **Location**: Line ~490 in the pfQuestInit frame's OnEvent handler

### route.lua
- **GPS Arrow Repositioned**: Changed arrow positioning from `SetPoint("CENTER", 0, -100)` to `SetPoint("TOP", 0, -10)`
- **Effect**: The quest navigation arrow now appears at the top of the screen (10 pixels down) instead of at the center
- **Location**: Line 305 in the pfQuest.route.arrow frame creation

## Technical Details
- Setup window bypass: Modified the conditional check that controls when the pfQuestInit welcome dialog is displayed
- Arrow positioning: Changed the anchor point from "CENTER" to "TOP" and adjusted Y offset from -100 to -10 pixels
- Both changes maintain the original functionality while providing a more streamlined user experience

## Benefits
- No more setup interruptions on first run
- GPS arrow positioned at top for better visibility during questing
- Maintains all original addon functionality
