app_queue: Fix raise_respect_min lost in copy_rules() breaking rN queue rules

app_queue: Fix raise_respect_min not copied in copy_rules() causing rN rules to be ignored.

`copy_rules()` never copied `raise_respect_min` into the per-call rule list, so the flag was always 0 when a timed penaltychange rule fired, making `rN` behave like plain `N` and raising members below `min_penalty` that should have been excluded.

Also fixes `update_qe_rule()` not propagating the flag from `qe->pr` to `qe`, and dropping the `r` prefix when saving back to `QUEUE_RAISE_PENALTY`.

Resolves: #1901
