Renames config dir env var to PMDAEMON_HOME and config directory name to .pmdaemon

Updates the old environment variable name used to override the default configuration directory from `PM2R_HOME` to `PMDAEMON_HOME`.

This change aligns the environment variable name with the project name and ensures consistency across the codebase, documentation, and examples.
