ViewTaxReceipt: ts usage fixes

Created by: coopsymbioticbot

Removes variables from inside 'ts' strings, which otherwise prevents the string from being translatable.

Note: avoid newlines inside 'ts'. Translators cannot know if the newline is required for formatting, or was just code formatting. If the code formatting is changed (ex: indented, then newline is moved around), it would break the translation. Although it's better to leave current strings as-is, because otherwise the strings will have to be re-translated.
