Fixes #39492: Replace enzyme test in SettingsTable, SettingsCell, SettingsName with RTL

[Lukshio]

@kfamilonidis please add more testing cases

[kfamilonidis]

Added 4 more tests that check the settings table values (instead of row headers that was before)

[Lukshio]

Summary

Good migration across SettingsTable, SettingCell, and SettingName. The author already responded to the earlier "please add more testing cases" feedback by adding 4 behavior-driven tests (cell text, cancel-exits-edit, Escape-exits-edit, select-submit). Solid overall.

Critical (must fix before merge)

• None

Suggestions (should fix)

• SettingsTable.test.js still builds its store with configureMockStore/mockStore (redux-mock-store). The project's testing guidelines call this out as deprecated for new tests in favor of a real store with initial-state fixtures. Since this PR already reworks the surrounding tests, consider swapping it out here (or note it as a deliberate, scoped-out follow-up).
• Several assertions use raw document.querySelector('button#administrator') / [data-ouia-component-id=...] instead of RTL's screen.getByRole/getByLabelText. This matches the pre-existing style in the file, so not a regression, but worth moving to accessible queries where a role/label exists, for resilience if ids ever change.
• Commit message uses Fixes #39492: ... - the documented convention (see develop history, e.g. Fixes #38653 - Fix settings show endpoint) is Fixes #XXXXX - description with a hyphen, not a colon.

Nice to have (optional)

• None beyond the above.

Checklist gaps

• redux-mock-store usage not addressed (see above).
• Commit message hyphen convention.

@Lukshio Replaced mock store with a real redux store.
I changed in the three interaction tests with role based assertions.
Left on data-ouia-* deliberately, with a comment noting why.
