Update Stirling-PDF v2.4.3 - Add Built-in Login Authentication

Description

Adds Stirling-PDF's built-in login authentication to improve security. Previously the app was configured without authentication, relying solely on network-level access control.

What Changed

Authentication Enabled:

• DOCKER_ENABLE_SECURITY: true
• SECURITY_ENABLELOGIN: true
• SECURITY_INITIALLOGIN_USERNAME: admin
• SECURITY_INITIALLOGIN_PASSWORD: $PCS_DEFAULT_PASSWORD
• Index page changed to /login

Why:

• Adds an additional security layer beyond network-level access
• Uses $PCS_DEFAULT_PASSWORD per CONTRIBUTING.md standards
• Users can change credentials after first login

Security Checklist

• Default authentication enabled with $PCS_DEFAULT_PASSWORD (no hardcoded credentials)
• Login credentials documented in tips (all 5 languages)
• Root user (0:0) justified in rationale.md - required for Java runtime and PDF tools
• Specific version tag: 2.4.3
• pre-install-cmd uses specific version tag (ubuntu:22.04)

Functionality Checklist

• Works immediately after installation
• Data mapped to /DATA/AppData/$AppID/ and /DATA/Downloads/
• cpu_shares: 50 (Standard Application)
• Resource limits: 5G memory (2G reservation), 1.0 CPU
• Fresh installation tested
• Uninstall/reinstall tested - data persists

Documentation Checklist

• Description in 5 languages (en_us, ko_kr, zh_cn, fr_fr, es_es)
• Tips updated with login credentials table in all 5 languages
• Icon, screenshots, thumbnail point to Yundera/AppStore@main
