Reorganize share UI with Easy Share on top

Move Easy Share (.casera file) section above Share Code section in the
invite users dialog. Both platforms now have consistent UI with both
buttons using the same filled button style.

iOS changes:
- Move share functionality into ManageUsersView
- Remove share button from ResidenceDetailView toolbar
- Redesign ShareCodeCard with Easy Share on top

Android changes:
- Update ManageUsersDialog with matching layout
- Connect share package callback to existing share function
