Precise Rota Week Selection for Enhanced Scheduling Clarity in Multi-Rotas

Introduce a feature in the Multi Rota system that allows users to specifically select a rota week by its start and end dates, similar to the current functionality available when copying rotas. This enhancement would replace the existing seemingly random display of rotas with a more user-defined approach. By enabling administrators to choose a particular week, it ensures they are viewing or editing the exact rota period they intend to, thereby reducing confusion and improving scheduling accuracy. This feature would be particularly beneficial in planning and organising rotas in advance, offering a clear and structured approach to rota management.
