feat: Add LuckPerms web editor references to mod deployment guide

Added references to LuckPerms web editor in two key sections:

1. Testing & Verification Section:
   - Added tip box explaining web editor
   - Command: /lp editor
   - Benefits: Visual interface, color picker, no typing errors
   - Reference to Subscription Automation Guide for details

2. WorldEdit Configuration Section:
   - Added RECOMMENDED method: Use web editor
   - Alternative: Console commands (for those who prefer terminal)
   - Clear signposting to full instructions in other guide

Why This Helps:
- Holly sees web editor option while testing LuckPerms
- Reminded that web editor exists when configuring WorldEdit perms
- Cross-reference to Subscription Automation Guide Part 3
- Choice between visual (web editor) vs terminal (console commands)

Maintains consistency between both deployment guides.
