Live sidebar counts and Liquid Glass

This release adds live resource counts to the sidebar and an experimental macOS Liquid Glass chrome.

🔢 Live Sidebar Resource Counts

• Badges: the sidebar now shows live counts of resources per type and namespace, kept in sync from the same watch feed when one is open, or a bounded LIST probe otherwise
• Toggle: a new Settings switch lets you turn resource counts off entirely
• Accuracy: counts no longer carry over across a cluster/namespace switch, and Helm release counts are read from secret metadata instead of full payloads
• Caret alignment: the group caret now sits right next to its title instead of floating before the count badge

🪟 macOS Liquid Glass Chrome (Experimental)

• New toggle: an experimental Settings switch enables a native Liquid Glass/vibrancy backdrop for the sidebar and tab bar on macOS
• Full-width status bar: the sidebar footer now lives in a glass status bar spanning the window, with the app name and version moved to the right and action buttons to the left
• Active tab accent: the active tab now gets an accent top border for clearer focus
• Deeplink copy: the status bar has a new button to copy a deeplink to the currently focused panel

🐛 Fixes

• Permissions: long apiGroup values are now truncated instead of overflowing their tag
• Compact header: the compact header toggle now uses corner icons
• Drag and drop: dropping a panel on the tab bar no longer leaves stale drag state behind
• Text input: macOS inline text prediction is now disabled app-wide

🧹 Misc / Chore

• Dependencies: bumped Wails3 and frontend dependencies
