- get_ticket now returns `links` (blocks / blocked_by / relates_to /
duplicates / duplicated_by, phrased from this ticket's side, limited to
linked tickets the user can see) and `blocked` (any open blocked_by).
- find_similar_tickets (tickets:read): the possible-duplicates finder, by
title or by an existing ticket (which is excluded from the results).
- link_tickets / unlink_tickets (tickets:write). Marking a duplicate only
records the link. unlink also finds a link stored from the other side
("B blocked_by A" for "A blocks B").
api/ticket_dependencies.php's list/add/remove logic moves to
services/DependencyService.php, used by both (same checks and messages).
DependencyModel's remove methods now return rows removed, so removing a
link that is already gone no longer writes a "deleted" audit row.
Also includes the port in ToolScopeMiddleware's resource_metadata URL
(matches the 401's; no effect on prod, which has no port).
