Add configurable color output support

[coderabbitai]

Context

As discussed in PR #140 (#140 (comment)), we should add support for configurable color output in the CLI.

Currently, the CLI uses hard-coded color output (e.g., the ColorizePhase function). We should consider making this configurable to give users control over when and how colors are displayed.

Potential approaches

• Optional color support similar to kubecolor
• Customizable flag like velero's approach
