Root cause

#854 added the sender-authentication options (require_spf, require_dkim, require_dmarc, check_blocklists, blocklists) to the email check form. The edit page shows them, loaded from the stored config. But the shared check form drops config from the PATCH of every passive check type on edit (it was written when the only passive config was the server-managed token). So the options showed, the save returned 200, and nothing was stored.

Fix

• check-form.tsx: an email check's edit PATCH now carries its config. Heartbeat and private-location edits still omit it (no editable key, and a read-only region).
• The server already keeps the stored inbound token when a PATCH leaves it out (preserveAbsentRedactedFields), so the address does not change.

Tests

• Backend: TestPatchingEmailAuthOptionsKeepsTheToken patches the options in, checks they are stored and the token survives, then clears them with an empty config.
• E2E: email-check-sender-auth.spec.ts now edits an existing email check, turns every option on, reloads the edit form, turns them off, and asserts the stored config and token after each save. Run against a side-car server: 2/2 passed.
• golangci-lint 0 issues, dash0 unit tests 2911 passed, lint:e2e and typecheck:e2e clean. The unscoped dash0 lint is red on base, unchanged here.
