fix: preserve original trim defaults for safe migration
- events_loop_seconds: 3600 -> 900 (matches old trim_every=15m)
- heartbeat_events_retention_period: 1 day -> 7 days (matches
PREFECT_EVENTS_RETENTION_PERIOD default so no events are pruned
more aggressively than before out of the box)

fix: add backward-compat alias for event_persister.batch_size_delete
Map the legacy PREFECT_SERVER_SERVICES_EVENT_PERSISTER_BATCH_SIZE_DELETE
env var to db_vacuum.events_batch_size via validation_alias so existing
operator configs continue to work after the trim migration.

fix(03-03): use unsigned 0xC000013A for Windows exit code, fix cwd fallback in EngineCommandStarter
- _STATUS_CONTROL_C_EXIT now uses 0xC000013A (unsigned) to match runner.py
- EngineCommandStarter accepts explicit cwd param; falls back to None (not
tmp_dir) when no storage is set, matching runner.py line 961 behavior
- Added tests for explicit cwd passthrough and storage-overrides-cwd
