refactor(planner): share the left panel tab and the selected place props in the trip planner page

The plan view and the tour planner view each drew the left panel's tab in
full, and the place inspector and the tour dialog each listed the same props
twice, once beside the panels and once in the phone-width sheet.

LeftPanelTab, a small presentational component at the bottom of
TripPlannerPage.tsx, now draws the tab for both views. It stays in the page
file so the physical left and right offsets keep being counted there. The
tour planner's tab passes `announced`, which keeps its aria-expanded and its
focus ring; the plan view's tab still has neither.

The page body now builds selectedPlaceProps (what the inspector and the tour
dialog both take), placeInspectorProps and tourDetailProps once and spreads
them. What differs stays at each call site: the desktop inspector's
onOpenBooking and panel widths, the sheet's edit and delete closing the
sheet, the desktop tour dialog's non-modal focus return and widths, and
canEdit and canAssign on every tour dialog.
