feat(ui): Add quick search filter to the Task Templates view

[akeelow]

Description

When working with a large number of Task Templates, manually scrolling through them becomes tedious and inefficient.
This PR adds a quick, client-side search input filter to the Task Templates table.

Changes Made

• Added a <v-text-field> in the Templates.vue toolbar for the search input.
• Bound the search query to the existing v-data-table's built-in search property.
• Added translation key search to en.js and ru.js localization files.

How to Test

1. Navigate to navigating to the Task Templates section.
2. Type in the text field at the top right of the toolbar.
3. The list is automatically filtered locally based on query criteria.
