Add Spatio-Temporal Datasets Support to GRASS Data Catalog GUI

Currently, the GRASS Data Catalog only queries standard spatial maps and bypasses the temporal database and STDS's entirely. As a result, Space Time Datasets are completely invisible in the catalog interface, forcing users to manage them exclusively via the command line. This project will extend the existing Data Catalog architecture to natively support STDS. A solution will be implemented to show STDS alongside the standard spatial maps, fetching and displaying STRDS, STVDS, and STR3DS objects inside their respective mapset trees. Additionally, the project will enhance Data Catalog functionalities, such as context menus and other operations, to fully recognize, search, and interact with STDS objects in the GRASS GUI. Beyond these GUI integrations, the project will also focus on resolving critical bugs and enhancing the functionality of core temporal tools to improve the overall user workflow.
