feat: inline resolve for sub-deadlines + milestone date tooltips

- DeadlineTimeline gains onResolveInline callback prop
- Milestone labels show small green checkmark button for resolvable items
- Clicking opens inline text input (motiv + OK/Cancel, Enter/Escape)
- RegistryEntryDetail wires resolve via onResolveDeadline prop
- Milestone date labels show "Data maximă: ..." on hover
- Auto-refreshes viewed entry after inline resolve
