Fix render-link query/fragment duplication on lookup failure

When `$.Page.GetPage` fails (e.g., a stale `.md` link), the original
implementation appended `?query#fragment` to `$url`, which still held
the unchanged `.Destination` string that already contained them —
producing duplicated query/fragment in the output. Move the append
blocks inside the `with $.Page.GetPage` block so they only run after a
successful resolution.
