Fix Database Graph Endpoint Routing Issue

Problem

FastAPI was incorrectly routing /databases/graph requests to the /databases/{database_id} endpoint, causing a UUID casting error since "graph" is not a valid UUID. This occurred because the parameterized route was matching before the specific graph endpoint route.

Solution

Reordered the route definitions to ensure specific routes are matched before parameterized routes:

1. Moved /databases/graph route before /databases/{database_id}
2. Maintained existing order of other parameterized routes

Changes

• Reordered route definitions in the following sequence:
  @router.get("/databases/graph")
  @router.get("/databases/{database_id}")
  @router.get("/databases/{database_id}/password")
