Update dependencies and remove golang.org/x/exp/slog imports.

This commit updates the dependencies in the project by replacing golang.org/x/exp/slog imports with log/slog. The changes were made in various files across the project, including main.go, metrics.go, configs.go, structs/clientStatus.go, structs/nodeStatus.go, and internal/model/bulletin_board/bulletin_board.go. Additionally, the changes were made in a few test files, including api_functions/functions_test.go. The rationale behind this change is to bring consistency in logging across the project, and to eliminate third-party dependencies where possible.
