[PM-9952][PM-9954] Minor assign collection fixes (#10190)

* disable organization selector when only one org is selected

* break long org names in assign collections copy

- applicable more in the browser implementation

* add `title` to each select option so a mouse over presents the name

- more applicable to the browser extension where names can overflow

* truncate options that overflow a select

* set max width of form fields to 100%
