Translate the status abbreviations shown outside battle

src/ui/SummaryMenu.lua:148 and src/ui/PartyMenu.lua:824 drew mon.status
(PSN/PAR/BRN/FRZ/SLP) as a bare literal, bypassing translation. Unlike
plain text, a mod translates status labels through the statuses content
registry (mod.content.statuses:patch(id, { label = value }), the same
registry src/battle/BattleState.lua:statusLabel already reads in battle.
Route both screens through the same lookup, extracted as
Status.hudLabelFor(statuses, id) and shared with BattleState:statusLabel
so the hudLabel-or-label fallback rule lives in one place, with the raw
status id kept as the fallback when no record overrides it.

Found along the way: Status.RECORDS' five vanilla entries duplicated
hudLabel = label ("FRZ", hudLabel = "FRZ", ...) for no functional
reason. Since hudLabelFor reads hudLabel before label, and
Registry:patch only overrides fields a mod actually passes, a
translation mod's label-only patch (the natural shape for a status
catalog carrying one string per id, with no separate hudLabel data to
patch) was silently shadowed by the untouched vanilla hudLabel -- the
translation was stored but never displayed, in or out of battle. This
affected BattleState:statusLabel too, before this change and
independently of it. Dropped the redundant hudLabel field from all
five vanilla records: it's declared optional in the schema, and
nothing in this codebase ever gives it a value different from label --
setting it here only recreated the shadowing trap for no observed
benefit. Left a comment above Status.RECORDS warning against
re-adding it.
