feat: phase 7 automation & realtime — scheduled jobs, domain events, SSE

Scheduled jobs (migration 00009): cron expressions + @every descriptors,
in-process scheduler (15s scan, missed-run collapse), signed HTTP POST
delivery (X-Primora-Signature), AES-256-GCM sealed secrets returned once,
run history with status/duration/http-code, manual execution, retention
pruning. Viewer reads, admin/developer writes.

Domain events: publishEvent fans document/object/issue/deploy/job
mutations to realtime subscribers and matching webhooks through one
path. Webhook event filter extended to job.run, document.*, object.*.

Realtime: GET /projects/:id/realtime/stream SSE with 25s keepalives and
?token=/?api_key= auth for EventSource clients.

Automation dashboard page: Schedules tab (CRUD, run history, manual run,
secret-once banner) + Live events tab (live badge, pause/clear). Demo
mode parity. primora jobs:* CLI group, six primora_*_job* MCP tools,
AutomationService in the generated client.

Fixes folded in: gzip middleware buffered SSE flushes (broke EventSource
on both streams — */stream now bypasses compression); event payloads
double-marshaled json.RawMessage as base64; compose hardcoded localhost
trusted origins so non-default ports broke sign-in; frontend auth base
URL baked an absolute localhost instead of resolving /auth on origin.

Verified live: stack up on :8085, signed delivery HMAC-checked at sink,
@every 30s schedule firing, run history rendering, document.created
landing in the live events feed.
