Plugin Config Refactor

Combining the plugin list and settings into one object would solve several problems:

1. Multiple copies of a plugin get unique config (e.g. rtl_433, Adaptec_HBA).
2. Solves potential plugin config naming mismatch
3. Enables abstraction of plugin config, reducing code duplication

Example config.py:

PLUGINS: Union[str, Tuple[str, dict[str, Any]]] = []

# Simple plugin with no config
PLUGINS.append("Uptime")

# Run 2 copies of the plugin with separate config
PLUGINS.extend([
    ("Adaptec_HBA", {"id": 1}),
    ("Adaptec_HBA", {"id": 2}),
])
