fix: RunAction task re-evaluation compared against partial input, not full config

Bug: After running an action (e.g. bitcoin's autoconfig), update_tasks was
called with the submitted form input — which for task-triggered actions is
filtered to only the task's fields (e.g. {zmqEnabled: true}). Other services'
tasks targeting the same action were then compared against this partial via
is_partial_of, so any task wanting a field NOT in the submission (e.g.
{blocknotify: "curl..."}) would incorrectly become active, even though the
full config still satisfied it.

This caused a cycling bug: running LND's autoconfig (zmqEnabled) would
activate Datum's task (blocknotify), and vice versa, despite the merge
correctly preserving both values in the config.

Fix: After running an action, fetch the full current config via
get_action_input (same as create_task and recheck_tasks already do) and
compare tasks against that.

The one-liner fix would have been to add a get_action_input call in the
RunAction handler. Instead, we extracted eval_action_tasks on
ServiceActorSeed — a single method that both RunAction and recheck_tasks
now call — because the duplication between these two sites is exactly how
this bug happened: recheck_tasks fetched the full config, RunAction didn't,
and they silently diverged.
