• feat: mask encrypted config values in SCT logs

Keep plaintext out of refresh and group-load logs by tracking encrypted keys and replacing values with length plus a per-process salted fingerprint.

• fix: keep config fallback and polarisconfig endpoint usable

Serialize actuator polarisconfig as safe DTOs so ClientId is reachable, honor local-file-root-path for remote cache, and continue startup from existing cache when the config server is unreachable.

• fix: attribute encrypted config by file for logs and ACK

Pass EffectiveValue.sourceFile to the SDK, register keys from ConfigKVFile.isEncrypted() on group add, and omit group DEBUG maps only when the composite file is encrypted.

• fix: mark non-Polaris effective values as EXTERNAL

Tell the SDK that command-line and env overrides are not config-center files, so ACK can keep those effective values when an encrypted file is also watched.

• chore(docs): 更新 CHANGELOG 链接至 PR 1818

• refactor: hide test-only encrypted key set reset

Keep clearEncryptedPropertyKeys() package-private so it is not part of the public API.
