feat(i18n): sync editor translations with pluralization support and new UI strings (#6565)

# Description of Changes

## What was changed

- Updated editor translation files across multiple locales.
- Migrated numerous count-based translation keys from legacy
`{{plural}}` handling to ICU-style plural forms using `_one`, `_other`,
and where applicable `_zero` variants.
- Added translations and localization keys for newly introduced features
and UI areas, including:
  - Stirling Agents
  - Chat interface and quick actions
  - Files management and folder organization
  - Desktop update workflow
  - Folder scanning warnings
  - Team and workspace management
  - Sharing and upload dialogs
  - Comparison status messages
  - Relative time formatting
  - Additional tool panel and update UI strings
- Added missing translation entries required by recently introduced
frontend functionality.
- Reorganized some translation sections to maintain consistency and key
ordering.

## Why the change was made

- To align locale files with the current frontend feature set.
- To support proper pluralization behavior across languages.
- To prevent missing translation keys and fallback text in newly added
UI components.
- To improve localization consistency and maintainability as the
application grows.
