feat(frontend): add script disable functionality with visual indicators

[AlphaLawless]

✍️ Description

This PR implements a script disable system that allows scripts to be temporarily disabled while remaining visible in the interface with clear explanations. Instead of removing scripts entirely when issues arise, they now display a prominent disabled state with contextual information about why they're unavailable and links to related discussions or fixes.

Key Features:

• Scripts can be marked as disable: true with a required disable_description explaining the reason
• Disabled scripts show a styled alert banner with the description (supporting URLs and code blocks)
• Installation section is hidden for disabled scripts
• Sidebar displays a "Disabled" badge with reduced opacity for easy identification
• JSON editor includes toggle and description field for easy management
• Includes example implementation with opnsense-vm.json

Problem Solved:
Previously, problematic scripts were removed entirely, causing confusion for users trying to find them. This new system keeps scripts discoverable while clearly communicating their status, enabling community contributions toward fixes and maintaining transparency about known issues.
