feat: Add git-control.sh wrapper for unified git services

[xaoscience]

📋 Description

This PR introduces a unified git-control.sh wrapper that consolidates access to all git-related workflow tools in Dev-Control. It also refactors inconsistent headers to use the shared print.sh library functions.

Key Changes:

• New git-control.sh wrapper: Unified interface for git workflow tools with categorized menu structure
• Header consistency: Replaced hard-coded box headers with print_header_success() from lib/print.sh
• Menu reorganization: dev-control.sh menu now organized by categories
• New alias: dc-git for quick access to the git services submenu

Consolidated Scripts:

The new git-control.sh provides unified access to:

• template-loading.sh (dc-init)
• create-repo.sh (dc-repo)
• create-pr.sh (dc-pr)
• fix-history.sh (dc-fix)
• licenses.sh (dc-licenses)

🧪 How Has This Been Tested?

# Test git-control.sh wrapper
./scripts/git-control.sh --help

# Test dev-control.sh menu
./scripts/dev-control.sh help

# Verify aliases
grep dc-git scripts/alias-loading.sh

⚠️ Breaking Changes

Menu option numbers in dev-control.sh have been renumbered to accommodate the new git-control option:

• Option 2 is now "Git Services (dc-git)"
• All subsequent options shifted by 1
• Option 9 (Containerise) moved to option "c"

📝 Additional Notes

The git-control.sh wrapper follows the same pattern as dev-control.sh but focuses specifically on git-related workflows. Users can access it via:

• dc-git alias (after running dc-aliases)
• ./scripts/git-control.sh directly
• dev-control.sh git command
• Menu option 2 in dev-control interactive mode
