Update ApplicationTableSeeder.php

[jajaramillo24]

This pull request expands the seeding logic in ApplicationTableSeeder to create multiple test application records with varying access rules and configurations. Instead of seeding a single application, the seeder now adds a diverse set of applications to better support testing different scenarios.

Key changes:

Seeding logic improvements:

• Replaces the single static Application::create call with a loop that seeds six different application records, each with distinct name, description, tenant_user_id, and access rules.

Test data diversity:

• Adds applications covering scenarios such as: no policy rules (full access), all countries with only preparedness v2 enabled, India-only access, USA-only access with legacy and/or preparedness v2 enabled, and combinations thereof.
• Some applications use dynamically generated keys via Application::generateKey(), while one uses a static key for testing purposes.
• Each application record now includes an is_active flag and a rules array to control access restrictions and feature toggles.
