feat(server): list a user's schedules in one request (GET /me/cron-jobs)

[L42y]

What

Adds GET /api/v1/me/cron-jobs — every schedule the caller owns, across the orgs they belong to, ordered by what runs next.

Why

GET /chats/:chatId/cron-jobs answers "what runs from this chat". There was no route for the other question — "what do I have scheduled" — so a client wanting that list had to ask every chat it knew about and keep the few answers that weren't empty. That is one request per chat to find a handful of jobs, and it degrades as a workspace grows: the client I hit this with capped its fan-out at 40 chats and still couldn't state a trustworthy count without paying for all 40.

Scope and safety

Ownership is already the mutation boundary for a job — requireCronJobAccess gates on ownerMemberId — so listing by owner grants no new reach. The route returns exactly the jobs the caller can already read and modify one id at a time. Membership is filtered to status = 'active', matching the other /me/* cross-org listings (/me/clients, /me/managed-agents).

The existing idx_cron_jobs_owner_created index covers the members join; ordering is next_run_at ASC, which puts paused jobs (next_run_at IS NULL) after the scheduled ones — the order a reader wants anyway, since a job with no next occurrence can't be sorted among ones that have one.

Tests

packages/server/src/__tests__/me-cron-jobs-list.test.ts covers:

• returns the caller's jobs across multiple chats, and not another user's;
• ordering by next run, with a paused job last;
• 401 without a signed-in user.

Verified: tsc --noEmit on packages/server passes, Biome clean.
Not verified by me: the integration tests need a live Postgres, and this environment has one running but no credentials I can use — so the new test has not been executed locally. It follows the existing useTestApp / createTestAgent patterns and should run in CI; if it fails there, the failure is mine to fix.
