Refactoring code complexity in src/middleware/render.js

[zanzoonh]

resolves #52

Fixed three errors in the code:

• Cognitive complexity of processRender function from 16 to 15 - by moving out part of the code into a different function
• Cognitive complexity of loadClientHeaderFooterData from 27 to 15 - by moving most of the code into separate functions, and doing early returns
• Deep nesting of the functions - by extracting the deeply nested functions and declaring them outside.
