This commit introduces comprehensive tracing functionality to the account management flow by adding calls to `fxTraceCompte` and `fxTraceCompteRedirect` at key points in the login and routing processes. The changes improve the tracking of user actions and session states, facilitating better debugging and monitoring of account-related activities. Additionally, the promoteur hub event retrieval function is updated to include tracing, enhancing visibility into hub interactions. These updates aim to improve maintainability and user experience in the account management system.
