[Bug 2150439] Re: Refactor UpdateManager.py: improve logging, structure, and error handling

[Arnab Patra]

Thanks for the feedback, that makes sense.

I understand that the patch is quite large and includes stylistic
changes that increase the review effort. I’ll avoid broad refactoring
going forward and focus on smaller, targeted improvements.

While reviewing the code, I did notice a couple of minor issues that
might be worth addressing individually:

- There are still a few places where `print` is used instead of logging
(e.g. in `_fetch_ua_updates` in the original code), which can make
debugging and log collection less consistent.

- Some exceptions are silently ignored (e.g. `except SystemError:
pass`), which could potentially hide failures and make issues harder to
trace.

If these are considered worthwhile, I can prepare small, focused patches
for them instead of a larger refactor.
