formattingand autowired constructors (#2557)

# Description
This pull request includes several changes aimed at improving the code
structure and removing redundant code. The most significant changes
involve reordering methods, removing unnecessary annotations, and
refactoring constructors to use dependency injection.
Autowired now comes via constructor (which also doesn't need autowired
annotation as its done by default for configuration)
