Description

Adds support for removing previously applied filters in the THF Browse component before applying new ones. Introduces a reusable po-tag DOM utility and extends the language pack with the new "Remove Filters" key across all supported languages.

Changes

tir/technologies/core/language.py

• Added remove_filters attribute to LanguagePack class.
• Mapped the key to localized strings for all supported languages:
  • English: "Remove filters"
  • Portuguese: "Remover filtros"
  • Spanish: "Eliminar filtros"
  • Russian: "Удалить фильтры"
• Also added missing Filters and Apply Filters entries for the Russian language pack.

tir/technologies/poui_internal.py

• _filter_thf_browse: Now calls _remove_filters_from_browse() before opening the filter panel, ensuring stale filters are cleared prior to applying new ones. Updated docstring to reflect that filters must be a list of dicts.
• _remove_filters_from_browse (new): Checks for a po-tag element inside kendo-grid matching the "Remove Filters" label and clicks it when found, then waits for the component to finish loading.
• _get_po_tag (new): Generic DOM helper that locates a po-tag element within a given CSS-selector container by matching its inner span text (case-insensitive). Returns the element or None.

Motivation

When _filter_thf_browse was called multiple times, previously applied filters remained active, causing incorrect or cumulative filter results. This fix ensures a clean state before each filter application.

Testing

• Verify that filters are correctly removed before new filters are applied in THF Browse.
• Validate that _get_po_tag returns the correct element when a matching po-tag exists.
• Validate that _get_po_tag returns None when no matching element is found.
• Confirm all language strings render correctly for EN, PT, ES, and RU locales.
• Ensure no regression in existing filter-related tests.
