Fix cypress test 5_3_People_Totals_Test.js

[pylipp]

Task

• make the cypress test 5_3_People_Totals_Test.js work. It didn't work in the original implementation in Add total row to people table showing number of beneficiaries #730
• the following errors appear

  1) People_Totals_Test
       Should display totals row showing number of beneficiaries:
     AssertionError: Timed out retrying after 4000ms: expected '<div>' to contain 'beneficiaries'
      at Context.eval (webpack://*******/./cypress/e2e/1_feature_tests/5_3_People_Totals_Test.js:15:43)

  2) People_Totals_Test
       Should update totals when filtering:
     AssertionError: Timed out retrying after 4000ms: Expected to find element: `input[type="search"]`, but never found it.
      at Context.eval (webpack://*******/./cypress/e2e/1_feature_tests/5_3_People_Totals_Test.js:37:11)

I'm also adding part of the source for the people.php page. Use it to fix the test assertions.
For 1) note that the words "Total" and "beneficiaries" appear in different divs.
For 2) note that the search input has type="text" and name="search", and that the search text needs to be submitted by clicking the button.
Use GPT-5 to solve this.
