fix: Enable anonymous context redaction in server custom/migration events

Consume the redactAnonymousAllEvents flag added to launchdarkly-java-sdk-internal:
bump the internal dependency and enable the flag when the server SDK constructs its
EventsConfiguration, so anonymous context attributes are redacted in custom and
migration_op events (server-side behavior).

Stacked on #194 (the internal change). Do not merge until
launchdarkly-java-sdk-internal 1.9.1 is released.
