fix(dashboard): widen mission card title and surface Plan New Mission CTA

- Stack mission cards vertically inside the sidebar so the title gets
  the full card width; action buttons drop to their own row below.
- Move the Activity timestamp out of the cramped stats row onto its
  own line.
- Replace the icon-only Sparkles button in the sidebar header with a
  full-width centered "Plan New Mission" button (icon + text). Mobile
  footer button uses the same label.

+Mission sidebar follow-ups for card density and CTA prominence.
+
+- **Wider title in the sidebar**: stack mission cards vertically inside the
+  sidebar so the title row spans the full card width instead of competing
+  with the action buttons. Action buttons now sit on their own row below.
+- **Activity on its own row**: the `Activity X ago` label moved out of the
+  cramped stats line into its own row above the progress bar.
+- **Centered "Plan New Mission" CTA**: the sidebar header now hosts a
+  full-width centered button with the Sparkles icon and "Plan New Mission"
+  text (instead of an icon-only button tucked in the corner). The mobile
+  footer button uses the same label for consistency.
