`run_or_resume` now records `JobRunArgs` in `params` on a Fresh open and
restores them on Resume, passing the restored args to the handler rather
than whatever the resuming caller supplied.
Two problems, and the engine is the only place both are guaranteed.
**A resumed run must not change mode.** Handlers read `args` on every
call, so a paused `?repair=true` import resumed by a plain trigger
silently continued as import-only: the deletion half never finished and
nothing reported it. `?deep=true` had the same hole — a paused bit-rot
scan resumed shallow while still presenting as the run that started
deep. `blobs_consistency` and `manifests_consistency` had hand-rolled
this for their own two flags; the three import jobs had not, and fixing
it per-handler means every future job remembering.
**The run row should say what it did.** For a destructive job, "did this
run delete anything?" is answerable only from `params`, which is what an
operator reads afterwards. Before this, a repair run and a discovery run
were indistinguishable in the history.
Deliberately not overridable on resume: adding `?repair=true` to a
resume would apply it to the remaining entries only, producing a run
that half-deleted. Cancel and start fresh is the honest way to change
your mind.
A missing key reads as false/None, so a run paused before this existed
resumes under-acting rather than deleting under a flag nobody gave it.
Failure to record the flags fails the run instead of guessing — acting
under unrecorded flags is the one thing worth refusing for jobs that
delete.
The flag list is hardcoded here. Letting each job declare its own
parameters — name, type, default — is the better shape and is its own
change.

The admin panel had no repair toggle wired to anything but a hardcoded
name list naming the two refcount tenants, so `thumb_derived_import` and
`thumb_attached_import` could not be run in repair mode from the UI at
all despite supporting it. And nothing in the job list said what any
given job does or whether clicking Run on production writes anything.
Three defaulted methods on `JobHandler` and `RecoverableJobHandler`:
fn description(&self) -> &'static str
fn mutates(&self) -> Mutates // Never | Always | OnRepairOnly
fn repair_description(&self) -> Option<&'static str>
`RecoverableAdapter` forwards them — the registry only holds
`dyn JobHandler`, so a tenant's metadata is invisible otherwise, and
falling back to the defaults would report every recoverable job as
read-only, including the ones that delete files.
Three values rather than a boolean because a job can be read-only by
default and destructive under `?repair=true`; a boolean answers wrongly
for one of its two modes, and `false` on something that unlinks files is
the dangerous direction to be wrong in. `repair_description` returning
`Option` collapses "does it repair" and "what does repair do" into one
method: presence gates the toggle, content is the confirmation text —
which the frontend cannot invent, since correcting a counter and
deleting sidecars are not the same warning.
`OnRepairOnly` with no `repair_description` is rejected at registration:
it claims to mutate only under a flag it does not support.
All 17 registered jobs declare all three. The panel now renders the
description under each name, badges read-only jobs, confirms before a
plain run of a mutating one, and offers the repair variant off the
backend flag instead of the name list.
Descriptions are English in the trait, next to the behaviour: one in
`locales/*.json` rots invisibly the moment a job changes, and a
translator cannot know what `manifests_consistency` reconciles. i18n can
layer on later keyed by job name with these as the fallback.

a job can be paused/resumed
a job as an exclusibity by it's name
if you want to run another job with same name:
either cancel the first one, or wait of it's terminaison
pause does not permit to run the other job, this can create
race conditions
