Fixes: #21686

When a circuit termination is reassigned to a different circuit, the previous circuit could retain a stale cached association. This change moves the cache update logic from the signal handler into CircuitTermination.save(), where the original circuit_id and term_side values can be tracked so the old cache is cleared correctly when either value changes.

Tests have also been added to cover the relevant cache update scenarios and help prevent regressions.
