fix(sharing): Align userid config key in UserPlugin with Manager

UserPlugin reads `shareapi_restrict_user_enumeration_full_match_userid`
(no underscore) while Manager.php and the frontend both use
`shareapi_restrict_user_enumeration_full_match_user_id` (with underscore).

This mismatch causes the "disable exact match by user ID" admin setting
to have no effect on actual sharee search results.
