RFR: 8372746: Some httpserver files could benefit from some formatting cleanup [v6]

[Daisuke Yamazaki]

> Hello mainteners,
> 
> I cleaned up inconsistent spacing across the httpserver codebase.  
> 
> 1. Removed extra spaces before parentheses in function and constructor declarations to make them consistent.
> 2. Applied the same rule to function and constructor calls.
> 3. Normalised other spacing based on the majority style already used in the codebase.
> 4. Left spots untouched where keeping the spacing improves readability.
> 
> **This PR only adds or removes spaces. No functional changes.**
> 
> If you think it would have been better to update only the documentation part and leave the logic untouched, please let me know.
> I split the commits, so I can easily revert the one that touches the logic.
