Restructure directories and UI components

[ParamBirje]

The directory structure and components structure is not efficient nor scalable. The currect directory structure was made by keeping the 'pages' directory structure in mind, but is irrelevant as the 'app' directory revamps the organisation of the project files completely.

Need to organize files and components accordingly that are easy to manage and will scale efficiently to a bigger codebase.

Here are the official docs:
Getting Started: Project Structure
Project Organization and File Colocation

Routes going through UI component refactors:

• /components Distribute local components that are in /src/components #15
• /user Refactoring components in /user route #4
• /jobs Refactoring components in /jobs route #11
