Establish consistent output styling across all commands

[betegon]

Summary

Create a unified design system for command output so all commands follow the same aesthetic pattern, making the CLI feel polished and professional.

Proposed pattern

Each command output should follow a consistent structure:

1. Header - Short, contextual title (e.g., issue ID + title)
2. Content - The main information, consistently formatted
3. Footer - Links, hints, or next actions

Tasks

• Audit existing command outputs for inconsistencies
• Define style guide (spacing, colors, dividers, alignment)
• Create shared formatting utilities for the pattern
• Update issue list / issue view to follow the pattern
• Update org list / org view to follow the pattern
• Update project list / project view to follow the pattern
• Update event view to follow the pattern
• Update auth status to follow the pattern
• Ensure JSON output remains consistent (not affected by styling)

Notes

The formatters/human.ts already has good foundations with formatDetailsHeader, divider, and color utilities. Build on these patterns.
