fix: address PR #747 review comments

- Fix warning box path lines being 2 chars too wide (BOX_CONTENT_WIDTH - 4)
- Wrap getClaudeAuthIndicators in try/catch to prevent 500 on auth success
- Convert dynamic import to static import for @automaker/platform
- Simplify verbose debug logging to log objects directly
- Remove unnecessary truthy checks on always-populated path strings
