[Feat] [4.x] Apache Support (Beta)

[RichardAnderson]

This pull request introduces support for Apache as a webserver alongside Nginx and Caddy, refactors the webserver configuration generation system for extensibility, and updates related logic throughout the codebase.

NOTE: Many updates in the PR improve support for additional web servers, and remove hard-coded elements and IDs.

Pull request overview

This PR adds Apache (beta) as a supported webserver alongside Nginx and Caddy, and refactors vhost/config generation to be webserver-driven via a configGenerator() abstraction. It also updates site settings behavior and SSH templates/tests to cover Apache-specific operations (install, splash, vhost generation, verification handling, logs, and basic auth).

Changes:

• Introduces App\Services\Webserver\Apache plus Apache SSH templates (install/uninstall, vhost CRUD, SSL creation, splash).
• Refactors webserver config generation via Webserver::configGenerator() and makes htpasswd path webserver-dependent (basicAuthDir()).
• Adds/updates PHPUnit coverage for Apache install, config generation, verification blocks, basic auth behavior, service logs, and vhost template defaults.
