Description

This issue highlights two problems:

• The placeholder text "Please post your updates here 😄" in the /agile-settings modal does not render the 😄 emoji visually.

• Translations using variable interpolation, such as poll_with_uuid_not_found: 'Poll with ID ${uuid} not found', do not support variable interpolation, leading to incorrect or incomplete text rendering.

Steps to Reproduce

1 Open the /agile-settings modal in the application.
2. Observe the placeholder text "Please post your updates here 😄". It does not render the smile emoji visually.
3. Trigger an event where the poll_with_uuid_not_found translation is used (e.g., fetching a poll with an invalid UUID).
4. Observe that the ${uuid} variable is not interpolated correctly in the translation text.

Expected Behaviour

• The placeholder text in the modal should render the 😄 emoji visually as a proper emoji (e.g., 😄).
• Translations with variable interpolation should correctly replace placeholders (e.g., ${uuid}) with the corresponding variable values.

Actual Behaviour
