Fixes four Important findings from the review of Task 12.
Corrected nine check `tab` values at the source (BillingChecks was already
correct; OnboardingChecks/ProvisioningChecks/DeliveryChecks all carried the
pre-redesign 'integrations' value, which is not a member of
Integrations::TABS): four onboarding checks now point at 'platform' or 'env'
depending on where their field actually is, five provisioning/delivery
checks point at 'services'. checkUrl()'s match-block resolver — praised as
correct for the six checks that point at a genuinely different admin page —
is unchanged; its `default` arm is now a pure safety net, not a route any
check actually relies on.
Wrapped the "Prüfen" button in @can('secrets.manage'): mount() admits
hosts.manage OR secrets.manage, but runCheck() requires secrets.manage alone,
so an Admin-role operator could see a button that 403s on press.
Fixed a docblock on HEARTBEAT_KEYS that asserted a staleness threshold was
kept in sync with OperationChecks::STALE_AFTER_MINUTES — that constant is a
key/settings-name map with no threshold of its own, and no such
synchronisation exists.
Three new tests, each confirmed red against a deliberately reintroduced
version of the bug it covers before being confirmed green: every check's tab
value against where its field actually lives, the run-check button hidden
from an operator who cannot press it, and Http::assertNothingSent() after a
plain page load.
