wip(#3001): remove submit layer, rescue power ops into job_queue/power.rs

TREE IS RED ON PURPOSE — there is no compiling intermediate between
deleting submit and converting every caller. Checkpoint commit so the
work is durable; do not "fix" it by restoring submit.

Done:
- JobQueue::submit -> JobQueue::insert (no source/reason/container;
  returns the ids insert_job names).
- submit.rs deleted. Its 6 pure chain builders + 3 async *_many
  gatherers were NOT wrapper code and are rescued into
  job_queue/power.rs (templates.rs documents power ops as living
  outside it, because their shape needs a live is_running read).
- Converted: meta_inputs 1, topology 2, permissions 3, auto_update 2,
  actions 3, lifecycle_handlers 3.
- Dropped source/reason at every converted site: nothing ever read
  NodeKind::Dag's fields (only `{ .. }` matches exist), so they are
  write-only. Dead reason-only locals deleted; the boot sweep's summary
  became a tracing::info! rather than being lost.

Remaining: dashboard/lifecycle_ops 7, server.rs 7, and the test suite —
tests.rs has its own submit() helper whose u64 return is used as the
handle to navigate the inserted DAG, so those need a different way to
find nodes, not a mechanical port.
