Subject: [PATCH] fix(servarr): replace spaces in arr user tags with `-`
 (#2231)

* fix: sanitize disallowed characters in arr tags

Updates the tag creation to normalize diacritics, replace spaces with hyphens and stip any
non-alphanumeric characters from display name

fix #2229, fix #1897

* refactor: improve display name sanitization in tag creation

* fix: include displayName in user selection for tag migration

* fix(migrator): retrieve all user fields in tag migration

This is a one time migration so performance is neglible. This should trigger the @AfterLoad hooks
which sets the `displayName`
