Split Metrics sub-tab settings into separate WordPress option groups:
- wp_prometheus_endpoint_settings for auth token
- wp_prometheus_selection_settings for enabled metrics
- wp_prometheus_advanced_settings for isolated mode
This fixes the bug where saving from one sub-tab would clear settings
from other sub-tabs due to all settings sharing a single option group.
