Marc-André Bombeck 06935256b0 feat(integrations): let the ledger hold every failing leg at once
`failing_leg` was one slot, so two legs of the same provider failing in
overlapping windows overwrote each other. The row remembered whichever failed
last, and that leg recovering then cleared an error the other one was still
causing — the ledger forgot a live failure and painted the card green over it.

The slot becomes a set. A failure adds its leg, a success removes its own, and
the error state, the per-kind buckets and the streak anchor clear only once the
set is empty. The array is ordered oldest failure first, so the last element is
the leg that wrote the message `last_error` holds; when that leg recovers while
others are still failing, the message is cleared rather than left describing a
leg that is now healthy.

An unattributed failure adds nothing and removes nothing. A single-leg provider
therefore behaves exactly as before, and a multi-leg provider no longer loses
what its other legs already reported.

The column never reached a client — it is absent from the status serialiser and
from the OpenAPI contract — so it is replaced rather than shimmed.
