feat(web): overbooking and vacation conflict warnings in AllocationModal

- New ConflictWarningPanel component: amber box with per-day overbooking
  table (capacity / already booked / new / overage) and sky-blue info box
  for vacation overlap. Overbooking section has an 'I understand' checkbox
  that must be ticked before Save is enabled; vacation overlap is
  informational only.
- AllocationModal: fires allocation.checkConflicts reactively when
  resourceId, dates and hoursPerDay are all set. Shows ConflictWarningPanel
  between form body and footer. Passes allowOverbooking: true to the
  createAssignment mutation when the user acknowledges. Acknowledgment
  resets whenever key fields change.
