feat: auto-create custom fields, add try/catch coverage, PHPDoc, and Pint formatting

- Auto-create 'Initial Operating System' and 'Initial SSH Key' custom fields
  via Database::ensureCustomFields() on module load, eliminating the manual
  modify.sql step
- Delete modify.sql (no longer needed)
- Add try/catch blocks around every DB operation and API call across all PHP
  files per CLAUDE.md error handling rules
- Add comprehensive PHPDoc to all classes, methods, and properties
- Set up Laravel Pint (laravel/pint) with Laravel-style preset for consistent
  code formatting across the codebase
- Add git pre-commit hook (hooks/pre-commit) that runs Pint on staged PHP
  files, auto-installed via Composer post-install/post-update scripts
- Simplify README installation to a single copy-paste command
