Normalize whitespace in .resx files

[xtqqczze]

This PR normalizes whitespace in .resx files across the repository.

Changes

• Remove trailing whitespace (via regex [ \t]+$).
• Ensure all files end with exactly one newline (using a Python script).

Motivation

The repository's .editorconfig specifies:

trim_trailing_whitespace = true
insert_final_newline = true

Many editors enforce these settings automatically. Without normalizing the existing .resx files, unrelated whitespace changes can show up in otherwise unrelated PRs.

By cleaning this up now, we reduce noise and friction in future contributions.

Notes

• Only whitespace was modified.
• No resource content or functional changes were made.

The Visual Studio RESX editor adds these whitespaces so this removes friction somewhere and adds it elsewhere.

Could we instead add a line that disables these editorconfig rules for RESX?

I think the Visual Studio RESX editor adds the whitespace to new files, not to existing files.

We already have many existing files that have the trailing whitespace removed.

No, it will add it if it's missing.

What is the editor's behaviour with respect to final newline?

I see, so this PR does indeed add friction.

Could you confirm whether this behaviour is in the new Visual Studio Resource Explorer, or the old Resource Editor?

It's the thing that shows up when one double clicks the resx file:
