refactor: consolidate duplicate logic across codebase

PHP (Module.php):
- Extract resolveServiceContext() helper — eliminates 15 repeated
  service/whmcsService/getCP/initCurl lookup chains (~200 lines saved)
- Extract static groupOsTemplates() — single source for OS template
  category grouping logic, used by both Module.php and hooks.php

PHP (Cache.php):
- Add filesystem cache fallback when Redis extension is unavailable
- Atomic writes with tmp+rename pattern for race condition safety
- extension_loaded() check instead of class_exists()

JS (module.js):
- Extract vfUrl() helper — replaces 18 identical URL construction strings
- Extract vfShowAlert() helper — replaces 25 repeated alert show/hide/class
  toggle patterns across all action functions

hooks.php:
- Use Module::groupOsTemplates(data, htmlEscape: true) instead of
  inline duplicate grouping logic (~40 lines removed)
