feat(ovhcloud): hold Riposte's on-call ladder in a VoIP call queue (1.1.0)

Riposte's pager can hand its on-call ladder to a marketplace instance, so that a
number published to clients rings whoever is on duty without the call ever
crossing the SOC's own trunk — and without spending one of its simultaneous
calls, which are sold in blocks and are the reason the PBX-side mode is too
expensive for a small deployment.

Three commands, and they are a contract rather than this integration's own
vocabulary: set_oncall_ladder (ordered numbers + ring_seconds), get_oncall_ladder
(what the carrier ACTUALLY holds, so a comparison can be honest) and list_calls
(the journal, after the fact). The pager offers whichever instances declare the
first one; the README now documents the contract for whoever writes the next
router.

Extends the existing ovhcloud integration rather than adding a second one: it
already carries the signed-request authentication, and making an operator enter
the same application key twice would serve nobody. Three telephony_* config
fields are added; every existing command is untouched, and an instance that
leaves them empty is exactly the OVHcloud reader it was before.

set_oncall_ladder RECONCILES rather than rebuilds. Agents are created when a
number has none, reordered by position, and anybody who drops off the ladder is
LOGGED OUT and removed from the queue — never deleted, because deleting throws
away whatever else the operator configured on that agent and they are on the rota
again next week. It also enforces the sequential strategy: publishing an ordered
list into a queue set to ring everybody at once is a lie that is invisible from
Riposte.

Two details that would each have cost an evening: OVH accepts no "+" in a
phoneNumber field, so E.164 is converted to the 00-prefixed form both ways; and a
service holding several queues is REFUSED rather than guessed, because guessing
publishes the on-call ladder into whichever queue the API happened to list first.

Verified against a stubbed API for the first publication and for a rota handover.
The signature, the error codes and the exact number format are only proved by the
first real call.
