chore(todo): fix owner lookup ref + completed-task seed validation (#2008)

Two app-todo defects found driving it end-to-end:

1. todo_task.owner was Field.lookup('user') — `user` is not a registered
   object/table (the platform user object is `sys_user`), so seed-time owner
   resolution flooded "no such table: user". Repointed to `sys_user` and
   dropped the unresolvable `owner: 'admin'` seed value (no stable seed key for
   the auth-created bootstrap admin).

2. The two `completed` seed tasks omitted `completed_date`, violating the
   object's own `completed_date_required` validation → they silently failed to
   seed (only 6 of 8 rows loaded). Gave them a completed_date.

Verified: 0 "no such table: user" errors, 0 rule_violations, all 8 rows seed;
validation still rejects a completed task with no completed_date (400);
aggregation/reports unaffected.

+chore(todo): fix two app-todo defects found driving it end-to-end — (1) `todo_task.owner` was a lookup to `user`, which isn't a registered object, so seed/owner resolution hit "no such table: user" (the platform user object is `sys_user`); (2) the two `completed` seed tasks omitted `completed_date`, violating the object's own `completed_date_required` validation, so they silently failed to seed (6 of 8 rows loaded). Repointed the lookup to `sys_user`, dropped the unresolvable `owner: 'admin'` seed value, and gave completed seeds a `completed_date`. Now all 8 rows seed; validation still rejects a completed task with no date. Example-app only.
