feat(tailscale): add connect/disconnect, exit-node and LAN-access controls (#2644)
* feat(tailscale): add connect/disconnect/exit-node/LAN-access backend The Tailscale backend previously exposed only read-only status (tailscale.getStatus, tailscale.refresh). This adds write actions through the existing tailscale.com/client/local integration: - tailscale.connect / tailscale.disconnect (EditPrefs WantRunning) - tailscale.setExitNode (EditPrefs ExitNodeID; empty id clears it and any legacy ExitNodeIP, mirroring `tailscale set --exit-node`) - tailscale.setAllowLanAccess (EditPrefs ExitNodeAllowLANAccess) The manager's client interface gains GetPrefs/EditPrefs; fetchState merges ExitNodeAllowLANAccess from prefs, and Peer exposes ExitNodeOption so the UI can list exit-node-capable peers. * feat(tailscale): expose the new actions in TailscaleService Adds connectTailscale/disconnectTailscale, setExitNode/clearExitNode and setAllowLanAccess wrappers, plus derived exitNodeOptions/currentExitNode and the exitNodeAllowLanAccess state. Write-action errors surface via ToastService. * feat(tailscale): add connection, exit-node and LAN-access controls to the widget The control-center widget toggle was a no-op. It now connects/disconnects, and the detail panel gains a connection status row with a connect/disconnect button, an exit-node picker and a LAN-access toggle.
