fix: ui fixes for panel selection modal (#11944)

* fix: ui fixes for panel selection modal

* feat(dashboards-v2): choose target section when adding a panel

Add a section picker to the New Panel modal so a panel can be placed in
any section (or the untitled root), not just the one the "Add panel"
action was triggered from. Sections are read from the cached dashboard
query via useDashboardSections (no refetch, no prop-drilling).

Picking a panel type now selects it (highlighted card) and reveals a
footer holding the section dropdown and an "Add Panel" button split
50/50; confirming shows a brief loader before navigating to the editor.
The chosen section's layoutIndex is threaded through
useCreatePanel.createPanel.

* fix(dashboards-v2): refine New Panel modal footer + section labels

- Keep the footer visible at all times; the "Add Panel" confirm is disabled
  until a panel type is selected (instead of hiding the whole footer).
- Footer layout: the section selector fills the available width and the
  confirm button takes its natural width (no more 50/50 split).
- Add a "Select panel type" label above the panel-type grid, matching the
  existing "Add panel to" label.

* chore: pr review fixes
