  -----------
  NMS-20100: copy-on-write destination paths, fresh role names, addressable names !smoke

DestinationPathManager mutated its TreeMap in place under the mutator's
lock while getPath/getPaths read it unlocked. Every change now applies to
a copy, persists that copy, and publishes the reference only on success,
which also removes the snapshot-and-restore code: a published map is never
mutated again, so unlocked readers always see a consistent snapshot.

Target validation read role names from the cached group config; user and
group names refresh on read but getRoleNames does not, so a role added by
hand or through the on-call roles API was rejected until an unrelated read
reloaded the file. Notification and destination-path names may no longer
contain '/', '\', '%' or control characters, which the HTTP firewall
rejects as a path segment, so such an entry could be created but never
edited or deleted; both editor dialogs flag the same rule inline.
