Add asset tag edit functionality to overview pageHEADmaster

Implemented the ability to view and edit the system asset tag directly
from the Overview page, including a modal dialog for editing, Vuex store
action for saving, and truncation in the app header.

Changes:
  - Added ModalAssetTag.vue component with:
    - Form input for editing the asset tag value
    - Vuelidate validation requiring a non-empty tag
  - Updated OverviewServer.vue to:
    - Display asset tag in the system information section
    - Add inline edit button using Carbon edit icon
    - Dispatch saveAssetTag store action with toast feedback
    - Refresh global system info after a successful save
  - Added saveAssetTag action to SystemStore.js using PATCH
    against the system path endpoint
  - Updated AppHeader.vue to truncate asset tags longer than
    30 characters with an ellipsis, preserving full value in
    the title attribute for accessibility
  - Added translation keys for asset tag label, modal title,
    and success/error toast messages in en-US, ka-GE, and
    ru-RU locale files

Testing:
  - Verified asset tag displays correctly in system info section
  - Verified modal opens, validates, and submits correctly
  - Verified PATCH request updates asset tag on the server
  - Validated success and error toast notifications display
  - Confirmed long asset tags are truncated in the header
