fix(i18n): sync locale fixes and no-wrap reformat

[somethingwithproof]

This PR consolidates and improves upon #296 and #291.

Changes:

• Syncs syntax and variable placeholder fixes for all locales.
• Fixes zh-CN full-width percent sign syntax errors.
• Standardizes all .po files with 'msgcat --no-wrap' as requested.
• Verified all language files pass 'msgfmt --check' with zero fatal errors.

Supersedes #296 and #291.

@somethingwithproof , now sv-SE.po. How does this happen?

[somethingwithproof]

The sv-SE conflict was a PO header timestamp. Weblate updated the PO-Revision-Date on develop after the branch was created, so the rebase hit a conflict on the header block. Resolved by keeping the upstream (newer) timestamp. No translation content was affected.
