Rename JSON keys to camelCase in site status output

[bcotrim]

Related issues

• Fixes STU-1271

Proposed Changes

• Add toCamelCase helper function to cli/lib/utils.ts for converting space and hyphen-separated strings to camelCase
• Apply the conversion to JSON output in site status --format=json (e.g., "Site URL" → "siteUrl", "Auto-login URL" → "autoLoginUrl")
• Table format remains unchanged with human-readable keys
• Update test expectations to validate camelCase JSON keys

Testing Instructions

1. Run unit tests: npm test -- cli/lib/tests/utils.test.ts cli/commands/site/tests/status.test.ts
2. Build CLI: npm run cli:build
3. Test JSON output: node dist/cli/main.js site status --format=json (keys should be camelCase)
4. Verify table format: node dist/cli/main.js site status --format=table (keys should remain human-readable)
5. Cross-platform testing completed on macOS and Windows ARM64

Changes LGTM and on macOS work well, but on Windows I get an error that "Selected folder is not added to Studio". Could you please double-check that --path property works well on Windows? Probably it's not related to this PR, but still.

Regarding code and macOS - LOGTM and works well 👍
