fixing some of the missed/ignored errors

[egorikas]

Why
Ignoring of errors is a bad coding practice that can lead to the non-expected results. Silent errors may cause serious disturbances to the application working.

What
Fixing part of the ignored/missed errors.

How

• Handling some errors explicitly.
• Providing a few ignores in places, where the fix has no sense.
• Providing a closers.Close function to log errors happening during closing of different objects.

Pull Request Overview

This PR improves error handling by addressing ignored/missed errors throughout the codebase. The primary focus is to explicitly handle errors that were previously being silently ignored, which could lead to unexpected application behavior.

• Introduces a new closers.Close utility function that logs errors during resource cleanup
• Replaces direct defer closer.Close() calls with proper error handling
• Adds explicit error checking for write operations and other critical functions
