feat: shared tile look for cards and pages, plus new page pieces in SDK 1.1.0

CHANGELOG.md

 ### Changed
 
-- Plugin cards placed on a tile grid take the dashboard look, with shared lines and no gaps
+- Plugin cards and pages use the dashboard look everywhere, with shared lines between sections instead of separate boxes with gaps
+- The Plugins tab and plugin pages use the same look
 - Line charts that cover a few minutes show seconds in their times
 - Plugins a new release adds to the image start on only when they are recommended. The rest are installed and left off for an admin to turn on

 This guide is for anyone, person or AI coding tool, building a Termix plugin. It ships inside
 `@termix-ssh/plugin-sdk`, so the copy in your `node_modules` always matches the SDK you have installed.

 - Small type: most text 11 to 13px.
 - No new modal dialogs. Ask with `useConfirm()`, open views in place with `InlineView`, and use
   `PanePrompt` for small prompts.
-- Every tab or panel sits in `PanelShell`. Lists use `PanelList` and `ListRow`, add with `AddButton`,
-  forms end with `FormFooter`, empty lists show `EmptyState`.
+- Every tab or panel sits in `PanelShell` (inside `PanelFrame` when it is a tab). Lists use `PanelList` and
+  `ListRow`, add with `AddButton`, forms end with `FormFooter`, empty lists show `EmptyState`, loading shows
+  `LoadingState`, and "not installed" or "no access" shows `NoticePanel`.
+- The tile look: page content sits edge to edge on the page background, with one line between sections and
+  no gaps, padding or card fill around them. The body of a `PanelShell` has no padding. Stack sections with
+  `TileStack` (or `TileColumn` when cards sit deeper), put numbers and small cards in a `TileWall` of
+  `StatTile` or `MetricCard`, and use `TileFrame` for a titled section. Cards drop their own box inside
+  these. Forms keep `PANEL.body` padding inside their section. An `InlineView` form made of `SectionCard`s
+  takes `stacked`.
+- Page views go in `PanelShell`'s `tabs` band as a `TabStrip`. `Segmented` is for filters and view modes.
+  A page with many sections uses `SideNav` on the left. Put the refresh button in the header with
+  `RefreshButton`, and the docs link with the `docs` prop.
+- States and data: `StatusBadge` and `StatusDot` (pass a state like "running" and the color follows),
+  `InfoGrid` for label and value pairs, `DataTable` for a plain table, `Pager` and `usePaged` under long lists.
 - Tile pages use `TileGrid` with `TileFrame` around each tile and `TilePicker` beside it while editing. Slots are
   `{ id, x, y, w, h }` on 12 columns (`h` null for the natural height); save them where your plugin keeps
-  preferences and run saved ones through `sanitizeTiles`. Add with `appendTile`. Needs Termix 26.11.1.
+  preferences and run saved ones through `sanitizeTiles`. Add with `appendTile`. While editing, show
+  `TileEditBar` over the grid. Needs Termix 26.11.1.
 - A dashboard card with `entries` can be placed many times: each entry has a title, a group and a `config` the
   card gets back as `config` (save changes with `setConfig`, keep it small). Operations Center uses this for
   status and action tiles.
-- Card grids use `DataView` with `ViewToggle`. Pass `columns` and `onColumns` to `ViewToggle` and the same
+- Card grids use `DataView` with `ViewToggle` (the cards share lines like a `TileWall`). Pass `columns` and `onColumns` to `ViewToggle` and the same
   value as `size` to `DataView`, so users can pick Auto (as many as fit) or a fixed number of cards per
   row. `usePluginPanelView` keeps the choice as `columns`. Older Termix versions ignore both props.
 - Forms: `TextField`, `NumberField`, `SelectField`, `SwitchRow`, `SecretField`, `SettingRow` and friends.
