refactor: create Squad

[sshanzel]

Changes

• This needs the API changes, so might be able to test it on local only.
• This is purely Create Squad page, don't mind the edit page, I will raise a separate PR for that pointing to this one.
• Tested locally both the dropdown and opening a public Squad ✅
• Dropdown component to have a disabled state.
• Refactored the Details component to be broken down into Sections. Some of the things you might see are purely copy-pasted.
