feat(v1.1.4): outbound HTTP SDK + cron triggers

HTTP (`http::*`):
- `HttpService` trait (picloud-shared) + reqwest-backed `HttpServiceImpl`
  (manager-core), wired into the `Services` bundle.
- SSRF deny-list applied to the resolved IP via a custom reqwest
  `dns_resolver` (covers every redirect hop + defeats DNS rebinding) plus
  a literal-IP check at URL-parse time. Scheme/port restrictions, request
  + response body caps (stream-with-cap), layered timeout. Error reason is
  a CIDR category, never the IP. `PICLOUD_HTTP_ALLOW_PRIVATE` dev override
  (logs a startup warning).
- Rhai bridge with three-arg split `verb(url, body, opts)` (resolves the
  brief's body-vs-opts contradiction; unknown opt keys throw). Body
  dispatch by type; response `#{status,headers,body,body_raw}` with JSON
  auto-parse; non-2xx does not throw.
- `Capability::AppHttpRequest` → existing `script:write` scope (no new
  Scope variant). `SdkCallCx` gains `script_id` (attribution + User-Agent).

Cron triggers (4th trigger kind):
- Migration 0017 widens the kind/source_kind CHECKs and adds
  `cron_trigger_details`. `cron`/`chrono-tz` parse + validate 6-field
  schedules and IANA timezones.
- `spawn_cron_scheduler` polls due triggers and enqueues to the universal
  outbox; the dispatcher delivers them (one-line match-arm extension).
  Catch-up fires exactly once per trigger per tick, not once per missed
  window. `ctx.event.cron` for handlers.
- `POST /api/v1/admin/apps/{id}/triggers/cron` reuses the v1.1.3
  cross-app + kind!=module target check.
- Dashboard: admin-gated Triggers tab (cron create form + list).

Follow-ups: redact module backend errors at the resolver boundary (log
original at error level); pin `rhai = "=1.24"`; CHANGELOG incl. retroactive
v1.1.3 cross-app-trigger security note. Version bumps: workspace 1.1.4,
SDK 1.5, dashboard 0.10.0.
