feat(i18n): add and reorganize translation strings

* Extract and relocate multiple UI strings into code-based contexts to improve
  translation coverage and maintainability (email, key-server, gpg-info,
  version-check modules).
* Introduce new, more descriptive EML and email-operation error/message
  templates to aid users and translators; add file/read warnings and integrity
  labels for email handling.
* Add new translation files and contexts for key-server sync and search dialog,
  and extend existing TS files with updated locations (moved from .ui to .cpp)
  so translations map to runtime text.
* Mark obsolete/vanished UI strings and prepare placeholders for untranslated
  entries, enabling translators to provide localized text without changing code.
* Facilitate future localization work and clearer user-facing diagnostics by
  centralizing message strings and expanding translatable content.o
