Updated the messaging and UI to clarify unavailability of host-level metrics, such as CPU, RAM, and disk space, in agentless mode. Added clear formatting and new functions to handle missing metrics gracefully in the frontend.
This commit introduces a detailed database overview endpoint and service, providing key metrics such as replication status, database sizes, and performance indicators. On the frontend, a new UI section displays these metrics along with improved forms and troubleshooting tips. Enhancements improve user experience by adding informative tooltips and formatting for byte and time values.
