fix(workspace-server): CP orphan sweeper closes deprovision split-write race (#2989)
The deprovision path marks `workspaces.status='removed'` BEFORE calling
the controlplane DELETE. If that CP call fails (transient 5xx, network
hiccup, AWS provider error), the DB row stays at 'removed' with
`instance_id` populated and there's no retry — the EC2 lives forever.
9 prod orphans accumulated over 3 days under this bug.

Adds a SaaS-mode counterpart to the existing Docker `orphan_sweeper`:
- 60s tick (matches the Docker sweeper cadence)
- LIMIT 100 per cycle so a sustained CP outage drains over multiple
  cycles without blowing the request timeout
- Re-issues `cpProv.Stop` for any workspace at status='removed' with a
  non-NULL `instance_id`. Stop is idempotent (AWS terminate on
  already-terminated is a no-op; CP's Deprovision tolerates already-
  deleted DNS) so retries are safe.
- On Stop success, NULLs `instance_id` so the next cycle skips the row.
- On Stop failure, leaves `instance_id` populated for next cycle.

The existing Docker sweeper is gated on `prov != nil`; the new sweeper
is gated on `cpProv != nil`. SaaS tenants get exactly one of the two,
self-hosted tenants get the Docker one — no overlap.

Why this shape over option A (CP-first ordering) or B (durable outbox):
the existing inline path already returns a loud 500 to the user when
CP fails — the only missing piece is automatic retry, which a 60s
sweeper provides without protocol changes, new tables, or new workers.
~30 LOC of production code vs. ~400 for an outbox. RFC discussion in
#2989 comment chain.

Tests:
- 9 unit tests covering happy path, Stop failure, UPDATE failure,
  multiple orphans (one-fails-others-still-process), DB query error,
  nil-DB defense, nil-reaper short-circuit, and the boot-immediate-then-
  tick cadence contract.
- Mutation-tested: status='running' substitution and removed-UPDATE-
  block both fail at least one test.

Out of scope:
- Backfilling the 9 named orphans — they'll heal automatically on the
  first sweep cycle after this lands; no manual cleanup needed.
- Long-term durable-outbox architecture — separate RFC.
