feat: add active processes management tab
Introduces a new "Active Processes" feature that enables users to view and manage background processes running on the PS5. Backend: - Add `payload_mgr_process_list_json` using `sysctl` with `KERN_PROC_PROC` to fetch the kernel process list and memory footprints. - Retrieve `appinfo` via `sceKernelGetAppInfo` to filter for user-spawned daemons (requires appid == `0000`). - Implement `payload_mgr_process_kill` utilizing `SIGKILL`. - Expose `/processes_list` and `/process_kill` endpoints. Frontend: - Add `ActiveProcessesView.jsx` with a real-time table of running processes. - Implement background auto-refresh every 15s to maintain the UI state. - Add safety nets to completely disable killing critical processes (`pldmgr.elf` and `elfldr.elf`). - Implement kill confirmation modal to avoid accidental terminations. - Integrate "Active Processes" tab with the sidebar and mobile bottom navigation.
