feat(tui): clarify monitoring continuity and quitting

 `fenris` opens the TUI dashboard.
 
+- **Continuity** — the service strip's continuity line (and `fenris status`) reports whether monitoring survives reboots: `monitoring: active in background · persists across reboots`, or `monitoring: does not start on next boot`.
+- **Paused vs. quit** — a full-width `monitoring: paused — deliberate disable` block means collection is stopped (`fenris monitor pause`); resume with `fenris monitor resume`. Pressing `q` only leaves the screen — monitoring keeps running in the background.
 - **Auth banner** — at launch, `privileged actions will prompt for authentication (polkit)` shows once and clears on the first refresh. Privileged actions elevate via polkit; Fenris never asks for sudo.
