fix: redact RabbitMQ URL in dial failure logs

[igor-kupczynski]

• The cannot (re)dial error logs in internal/msgqueue/rabbitmq/channel_pool.go printed the raw RabbitMQ connection URL, potentially leaking the username and password into logs (and any log aggregation) whenever a dial failed — e.g. during credential rotation.
• Added a small redactURL helper (stdlib net/url + URL.Redacted()) that masks the password as xxxxx; unparseable URLs log <unparseable url> instead of the raw value. The redacted URL is computed once in newChannelPool and used at both log sites, keeping host/port visible for debugging.
