Add functionality to search bar (student view)

[JDC-horizons]

Requirement:
user should be able to type into search box on top bar and search for other users by name.

Component:
search bar exists already in pages/dashboard/index.js.

Logic:

• user can type name or set of names split by space
• when search bar not empty, search button enables and changes visuals (i.e. change color)
• current search text stored in state (this is already enabled)
• search should occur when user clicks search or hits enter.

Search requirements:

• needs event handler to trigger search when above actions are taken.
• sends GET request to /users?search={string}
• use state variable in same file as event handler to track isSearching, default is false, when search happens it should change to true. search should check this variable to ensure it is false before searching to avoid simultaneous searches.
• while isSearching is set to true, search button should be disabled again to prevent more searches being sent.

Errors:

• if error occurs, change isSearching to false.
• error can be displayed using an alert or similar message.

On success:

• isSearching should be set to false.
• results stored in state, using context so they can be used by the results page as well.
• user is navigated to a results page (issue Create search results page (student view) #27)

1. are you going to create a component for this (if yes, what name for hte component, where is it going to be instantiated and what file); if not, what file is going to be touched and where is the component instantiated
2. what is the API calls you are going to do: is it a GET /??? with a query parameter or with route params or with a POST with a json payload? -> need details of what the api request is with the expected response
3. what are you going to do with the fetch results?
4. what are you going to do with any errors? how are you going to display them?
5. are you going to disable sending / pressing enter if we are waiting for the server to respond?

Looks good just missing info about what happens when search is in progress that @dogezen mentioned .i.e disable submit button while waiting
