refactor: move ellipsis and punctuation into i18n translation strings (#8573)

## Summary

Move ellipsis and punctuation characters into i18n translation strings
for proper internationalization support.

## Changes

- Add 12 new translation keys with punctuation included:
- Placeholder keys with trailing ellipsis (e.g.,
`searchNodesPlaceholder: "Search Nodes..."`)
  - `downloadWithSize` with interpolation: `"Download ({size})"`
  - `completedWithCheckmark`: `"Completed ✓"`
- Prompt keys with colons (e.g., `enterNewNamePrompt: "Enter new
name:"`)
- Update 20 files to use new translation keys instead of string
concatenation

## Review Focus

This eliminates string concatenation patterns like `$t('key') + '...'`
that break proper internationalization, since different languages may
use different punctuation or may not need ellipsis/colons in the same
contexts.

Fixes #7333
