* fix(telephony): handle Cloudonix CDR payloads missing session/disposition
The /cloudonix/cdr webhook is a public, unauthenticated endpoint that parses
arbitrary external JSON. It dereferenced cdr_data.get("session").get("token")
unconditionally, so a partial or malformed CDR payload that omits "session"
(or sends "session": null) raised AttributeError -> HTTP 500. The existing
"Missing call_id field" guard right below it was unreachable because the crash
happened first.
StatusCallbackRequest.from_cloudonix_cdr had the same fragility plus a second
one: data.get("disposition", "") returns None when the key is present-but-null,
and None.upper() then crashed.
Navigate both fields defensively so missing/null values fall through to the
intended graceful error path instead of crashing. Adds regression tests
covering missing session, null session, null disposition, and the well-formed
mapping path.

Transfer-context lookup by original_call_sid ran
`redis.keys("transfer:context:*")` and iterated every match — an O(N)
blocking scan on call-control hot paths, duplicated across the ARI
manager and the Twilio/Telnyx conference strategies.
Maintain a `transfer:by_call_sid:{original_call_sid}` -> transfer_id
secondary index, written and cleared alongside the context in
store/remove, and resolve lookups with a direct GET. Route the
Twilio/Telnyx strategies through the manager so the lookup lives in one
place (also dropping per-call ad-hoc Redis connections).
Closes#328
