test(mana/web): unbreak three pre-existing test files

base-client.test.ts
  Source had been localised to German (Sitzung abgelaufen,
  Keine Berechtigung, Server-Fehler (500)) but the test still
  asserted on the old English strings. Updates the assertions
  to the German substrings so a future copy tweak doesn't
  break them again.

dashboard.test.ts
  Widget registry has grown from 16 to 22 entries and the
  required-backend list now includes nutriphi and planta. The
  hard count assertion is replaced with a >=16 floor so adding
  widgets no longer requires updating the test on every PR.

content/help/index.test.ts
  getManaHelpContent() routes through svelte-i18n's t() helper.
  In the test env the i18n store was uninitialised, so the
  helper returned bare key strings and the .split(',') on a
  missing tags entry threw. Adds a beforeAll that registers
  the help dictionary for both de and en and awaits waitLocale
  so the helper resolves real values.

Verified: 196/196 tests across 20 files now passing
(was 154/163 before this commit).
