fix(dashboard): use DS Button prefix/size API instead of inline icons

@nous-research/ui@0.18.2 Button is grid-based: size=xs is an
aspect-square icon-only box, and icons belong in prefix/suffix.
The dashboard used shadcn-style size=xs + inline <Icon/> text
children, which forced text buttons into broken tall squares
(Configure, Run setup, Select, Save keys) and split icon/label
across grid columns elsewhere (Schedule it, Prune/Delete actions).

Move leading icons to prefix and size text buttons as sm/default.
For the post-setup spinner, drive the spin from a button-level
[&_svg]:animate-spin selector since the prefix slot clones the
icon and overwrites its className.

- ToolsetConfigDrawer: Select, Save keys, Run setup
- SkillsPage: New skill, Configure
- AutomationBlueprints: Schedule it
- SessionsPage: Prune old sessions, Delete empty, Delete selected

+# Epic's official "Unreal MCP" plugin (internal id ModelContextProtocol)
+# embeds an MCP server inside the running Unreal Editor process and serves it
+# over local HTTP. There is nothing to install on the Hermes side — the user
+# enables the plugin in-editor and the server binds to 127.0.0.1. Hermes's
+# MCP client just connects to the URL.
+#
+# Default bind is http://127.0.0.1:8000/mcp (port + path are configurable in
+# Editor Preferences > General > Model Context Protocol). If you change the
+# port/path in-editor, edit the url in mcp_servers.unreal-engine afterward.

+  This entry connects to Epic's official Unreal MCP plugin, which runs INSIDE
+  the Unreal Editor. Before Hermes can connect:
+
+    1. Open your project in Unreal Editor 5.8+.
+    2. Edit > Plugins, search "Unreal MCP", enable it, restart the editor
+       (the Toolset Registry dependency enables automatically).
+    3. Edit > Editor Preferences > General > Model Context Protocol, turn on
+       "Auto Start Server" (or run `ModelContextProtocol.StartServer` in the
+       editor console). It binds to http://127.0.0.1:8000/mcp by default.
+
+  Start Hermes AFTER the editor's server is running so the tools are probed.
+  If you changed the port or URL path in Editor Preferences, update the url in
+  mcp_servers.unreal-engine to match.
+
+  Status: Epic ships this as EXPERIMENTAL. The server runs Tool calls serially
+  on the engine game thread — avoid issuing overlapping calls.
+

+ * A completion that merely appends trailing whitespace to an already-complete
+ * command (e.g. `/exit` → `/exit `, the trailing space the gateway adds so the

+ * — otherwise every slash command needs an extra keypress: type → Enter
+ * completes the name → Enter adds the space → Enter finally submits. Treating a
+ * whitespace-only delta as "already complete" collapses that back to the
