* Add TestDesanitizeRemovesAllFakeSettings to catch future omissions
Walks every string field in the config after a Sanitize+desanitize
round-trip and fails if any still holds FakeSetting. This catches the
case where a field is added to Sanitize without a corresponding
desanitize entry.
* Fix ElasticsearchSettings.ClientKey being incorrectly masked as a secret
ClientKey is a file path, not a secret value. Masking it caused the
asterisk string to be persisted to the database on config writes, which
broke TLS client auth on restart.
* Fix desanitize missing entries for fields added in 504fb96fdd98
504fb96fdd98 masked five fields in Sanitize without adding the
corresponding desanitize entries, meaning a config save through the
API would permanently overwrite those fields with FakeSetting:
- FileSettings.ExportAmazonS3SecretAccessKey
- ServiceSettings.GoogleDeveloperKey
- ServiceSettings.GiphySdkKey
- CacheSettings.RedisPassword
- AutoTranslationSettings.LibreTranslate.APIKey
* fixup! Add TestDesanitizeRemovesAllFakeSettings to catch future omissions
* fixup! Fix desanitize missing entries for fields added in 504fb96fdd98
