Update the snapshot tests for the opt-in gate.

The enabled-path tests clear storage but do not opt in, so sendDailySnapshot() returns before gathering. The full Vitest run can fail. Seed consent, retain a no-consent test, and use an in-memory choice for the storage-error test.

   storage.clear();

Review comment at @src/lib/analytics.ts at line 27:
Update the snapshot tests for the sendDailySnapshot opt-in gate: seed consent for enabled-path tests, retain coverage confirming no consent gathers or sends nothing, and enable analytics through the test’s in-memory choice before stubbing localStorage to throw in the storage-error test.
