Monitoring sidebar toggle, Prompts-style Tools results, and icon-button UI polish (#1661) (#1662)

* feat(web): single header MonitoringToggle + Prompts-style Tools results (#1661)

Consolidate the monitoring column's open/close affordances into one header
toggle, and align the Tools/Prompts result panes and the sidebar log layout.

- Add a single `MonitoringToggle` in the header, to the right of the theme
  icon. It opens/closes the monitoring column and only shows when a server is
  connected OR a connect attempt failed (wide viewport + a monitor tab
  available) — the same availability rule the column uses.
- Remove the scattered pin/close icons: delete `PinColumnButton`; drop `onPin`
  from the Logs/Protocol/Network/Console screens and their stream panels; drop
  `onOpenMonitor` from the server list; remove the close button from
  `MonitoringControls`/`MonitoringScreen`.
- Tools screen: remove the "Results will appear here" placeholder pane. Results
  now replace the input form in a single content pane (the Prompts pattern),
  with a top-left X (ToolResultPanel) that dismisses them back to the form;
  form values are preserved for a re-run.
- Prompts screen: the argument form fills the content pane width (drop the 40%
  cap), matching the Tools input.
- LogEntry: add a `compact` two-line layout (time/level/logger on line one,
  message wrapping below) used by the embedded monitoring-column Logs.

* polish(web): tooltips on icon buttons + rename "monitoring column" → "monitoring sidebar" (#1661)

- Add Mantine `Tooltip`s to the icon-only controls: Client settings, Theme
  (dynamic light/dark label), the monitoring-sidebar toggle, the list-level and
  per-entry Expand/Collapse toggles, the Pin/Unpin toggle, and the Replay
  button. Labels mirror each control's existing aria-label.
- Rename the feature term "monitoring column" → "monitoring sidebar" across the
  user-facing labels (Open/Close/Resize), comments, and tests, so the UI calls
  it a sidebar consistently.

* review: consistent sidebar wording + reuse MonitoringToggleProps (#1661)

Address the two optional notes from the PR #1662 review:
- Make the MonitoringToggle JSDoc voice consistent ("sidebar" throughout,
  no lingering "column").
- Drop ViewHeader's duplicate `MonitorToggleProps` and reuse the element's
  exported `MonitoringToggleProps` as the single source of truth.

* feat(web): slide-in/out animation for the monitoring-sidebar toggle (#1661)

The header MonitoringToggle now animates in/out via a Mantine Transition whose
in/out styles drive width + margin-left (plus opacity/translateX): as its slot
grows from 0 → the 36px icon, the flex-end header row reflows and pushes the
theme + client-settings buttons one slot to the left; the exit reverses and they
slide back over. A negative margin-left while collapsed cancels the row gap so
the theme icon stays flush-right when the toggle is absent. Only appearance/
disappearance (connect / disconnect / narrow viewport) animates — opening or
closing the sidebar leaves the toggle in place.
