Refactor plugin configuration examples and improve formatting in documentation

- Replaced `config.yml` with modular configuration examples: `config-basic.yml`, `config-certbot.yml`, `config-deny-pages.yml`, and `config-jwt-validator.yml`.
- Improved examples with detailed usage instructions, prerequisites, and testing steps for each configuration.
- Fixed indentation and formatting inconsistencies across plugin files and HAProxy configuration generation.
- Streamlined README comparison table for static vs. dynamic discovery.
- Updated `docker-compose-jwt-validator.yml` to correct audience key formatting.

+# Certbot/Let's Encrypt Configuration Example
+#
+# Demonstrates:
+# - Automatic SSL certificate generation with Let's Encrypt
+# - HTTP to HTTPS redirect
+# - Certificate renewal
+#
+# Prerequisites:
+# 1. Public IP address with ports 80 and 443 accessible
+# 2. DNS records pointing to your server:
+#    example.com -> your-server-ip
+#    www.example.com -> your-server-ip
+#
+# 3. Set environment variable:
+#    EASYHAPROXY_CERTBOT_EMAIL=your-email@example.com
+#
+# 4. Mount this config:
+#    -v ./conf/config-certbot.yml:/etc/haproxy/static/config.yml
+#
+# 5. Persist certificates:
+#    -v ./certs/certbot:/certs/certbot
+#
+# How it works:
+# - EasyHAProxy requests certificates from Let's Encrypt via HTTP-01 challenge
+# - Certificates are stored in /certs/certbot/
+# - Certificates auto-renew when needed
+#
+# Note: Let's Encrypt has rate limits. Use staging environment for testing:
+#       EASYHAPROXY_CERTBOT_AUTOCONFIG=staging
