Luca e308204808 feat: undo button for trip planner ...

Implements a full undo history system for the Plan screen.

New hook: usePlannerHistory (client/src/hooks/usePlannerHistory.ts)
- Maintains a LIFO stack (up to 30 entries) of reversible actions
- Exposes pushUndo(label, fn), undo(), canUndo, lastActionLabel

Tracked actions:
- Assign place to day (undo: remove the assignment)
- Remove place from day (undo: re-assign at original position)
- Reorder places within a day (undo: restore previous order)
- Move place to a different day (undo: move back)
- Optimize route (undo: restore original order)
- Lock / unlock place (undo: toggle back)
- Delete place (undo: recreate place + restore all day assignments)
- Add place (undo: delete it)
- Import from GPX (undo: delete all imported places)
- Import from Google Maps list (undo: delete all imported places)

UI: Undo button (Undo2 icon) in DayPlanSidebar header. PDF, ICS and
Undo buttons all use custom instant hover tooltips instead of native
title attributes.

A toast notification confirms each undo action.

Translations: undo.* keys added to all 12 language files.
