i.atcorr: Fix uninitialized variable

[ShubhamDesai]

This pull request addresses uninitialized variable issue for all cpp files in imagery

Issue:
i.atcorr/main.cpp:213:16: error: Uninitialized variable: rbitem.ti [uninitvar]
return rbitem;

Changes Made:
Initialized the RBitem struct to zero to ensure all members, including nested structures, are properly initialized.

There was only one file left?

There was only one file left?

yes in imagery folder there is only one cpp file left other files are c file. So now i am grouping folder wise and programming language wise

See the new error here (and build failure) (ignore the garbage of the html file, it seems like unsynced output of parallel tasks):

let me check

i did the changes i think because it has two nested struct members it was not initializing everything.
