Fix typos and spelling errors across codebase (#156270)

Corrected various spelling mistakes such as 'occurred', 'receiver',
'initialized', 'length', and others in comments, variable names,
function names, and documentation throughout the project. These
changes improve code readability and maintain consistency in naming
and documentation.
