dsh-musage-card: DSH Sidebar Multi-Provider Usage/Balance Glass Card

`dsh-musage-card` is a locally forked plugin designed to integrate usage monitoring for multiple API providers into the DSH interface. It is pinned in the sidebar, supports 11 providers, and automatically toggles between displaying a balance or a progress bar based on the current model. The plugin provides a one-click browser login feature (Windows only) for cookie-based providers and supports manual configuration. Clicking the card refreshes the data, helping users avoid the hassle of frequently switching settings to check balances.
