I should be able to see more details about Org record

- [x] create tabbed show page (separate example)
- [x] create the first tab: grid with users from the given org
- [x] add address fields to the Org
- [x] fix grid resizing issue
- [x] create the second tab: ability to edit an address
- [x] add other org fields (should look the same as edit with tabs but enable the form above the tabs for editing name, num and phone)
