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.
