fix(recipes): polish deleted-LoRA reconnect panel UI

- fix .reconnect-input overflow (calc(100% - 20px) -> border-box 100%)
- replace nested-card border/background with a dashed top separator
- route reconnect copy through translate(); add recipes.resources
  .reconnectInstructions/reconnectExample/reconnectPlaceholder keys
  and translate them in all 9 locales
- show reconnect failures inline in the panel (role=alert) instead of
  a transient toast; errors clear on input/show/hide
- drop dead .reconnect-instructions code CSS; add regression test
