Drive SIP plans through the shared order pipeline (3d-6)

Advance executes due periods as real subscription orders: each due
trade date claims a sip_executions row (PRIMARY KEY plan_id+trade_date
makes same-plan same-day runs atomic), places the order through
CreateSubscriptionOrder with a deterministic idempotency key
(sip:{plan}:{date}) and the period's trade date, then confirms through
the shared ConfirmSubscriptionOrder pipeline with key
sip-confirm:{plan}:{date} — identical freeze/fee/units math as manual
orders, nothing bypasses confirmation. Outcomes: succeeded,
pending_nav (cash stays frozen; later drives retry the confirmation
once the NAV lands), insufficient_cash (no order placed, period fails
visibly, reruns keep the marker), failed. Plans roll their
next_trade_date past the processed window and repeats of the same
endDate replay recorded executions instead of re-debiting.

Domain adds SipPolicy.advancePlan (due-date enumeration; weekends-only
trading-calendar approximation, noted in code). POST
/funds/{id}/sip/advance {endDate?, limit?} drives execution on demand
(no daemon). Plan responses/rows now carry last execution status/date;
front-end shows 已执行/待净值/现金不足 per plan. Optional
tradeDateOverride/anchorOverride keep manual flows untouched.
