TJK: Apply reviewer ru/tg translation corrections for UI labels

📝 Implementation

Replaces machine-translated Russian (messages_ru.properties) and Tajik (messages_tg.properties) values with native-speaker corrections supplied on the ClickUp task, covering inventory, report, and dashboard labels.

• Applied to 143 message keys (129 ru / 122 tg values changed) — every key whose English source value exactly matches a reviewed string.
• System enum status codes left unchanged (enum.ActivityCode.CYCLE_COUNT, enum.TransactionCode.PRODUCT_INVENTORY, enum.InventoryLevelStatusCsv.IN_STOCK) — those carry system meaning and are handled separately.
• Dashboard count captions (Products / Items / Requests / Purchase Orders) had two grammatical forms in the source; used the nominative form since the caption renders under a number and the stack has no pluralization. Flagged for the reviewer in case they prefer the alternate.

Only the two .properties files are touched — no upstream code changes.

✨ Description of Change

Description: Corrects Russian and Tajik UI translations for the Tajikistan deployment using the reviewer-provided glossary. Values are stored as \uXXXX escapes to match the existing bundle format; key set, ordering, and file structure are unchanged.

📹 Screenshots/Screen capture

Verified live on localhost with the Russian locale — dashboard, stock movement lists, and menus show the corrected labels; old machine-translated values no longer appear.

🔥 Notes to the tester

• Switch the session language to Russian or Tajik and check the Dashboard, Inventory menu, Reports, and Stock Movement screens.
• The Inventory Summary dashboard chart still shows English status labels — this is pre-existing (those labels are hardcoded, not read from the translation bundle) and out of scope for this change.
