Introduced standardized error response formats for API errors, including middleware for consistent request IDs and exception handlers. Updated the frontend to parse and process these error responses, and documented the error format in the README for reference.
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.
