fix(native-chat): plain wording for chat errors and status rows (#24594)

* fix(native-chat): plain wording for chat errors and status rows

Replaces Orca-internal words (host, journal, transcript, outbox, process,
unverifiable, "no contact", byte budgets) in native chat refusals, status
rows, the skills menu, subagent and background-task state labels and the
history-load error with plain language, and routes the two hard-coded
English composer errors through translate(). Copy only; no behaviour change.

* fix(native-chat): match chat copy to what happens and to the sidebar's words

- The held-message row says Orca keeps checking, which it does: the idle
  sweep retries the unproven stop and a landed retry sends what waited.
- An unsettled earlier message reads as unconfirmed, not undelivered.
- The skills-unavailable line names SSH chats, its only cause.
- Subagent and background-task rows say "no recent update", the sidebar's
  words for the same state, and "status unavailable" after a count; the
  row no longer repeats the state as a reason.

* test(native-chat): find the repair row by its own text, not the old wording

* fix(native-chat): word the history-repair and too-large rows in the reader's language

Both rows were finished English the host wrote into the chat, so nothing could
translate them. Each now names itself with a presentation, the way the
compaction row does, and the chat says it through translate(). The English text
stays on the row for clients that predate these presentations and for the phone.

* fix(native-chat): say composer send errors with the chat's notice sentences

The composer's two errors had their own wording file beside the sentence table
every other chat notice uses. The send outcome now carries notice parts, worded
by the same function as the rest. A refused redelivery says "Orca couldn't
confirm your message reached the agent. Check the chat, then send it again if
needed." (the same sentence the failed-send rework uses), and a message this
client couldn't store says "Couldn't save your message. Try again."

* fix(native-chat): drop the retry line, keep one name for a lost task, and say only true causes

- The history error pane no longer adds "Orca keeps trying to load this chat."
  under its title: the read still retries on its own, but the pane says only
  that the chat didn't load.
- A write refused as unsupported asks for an Orca update only when no reason
  came back, which means the host is older. A named reason (a location or agent
  that can't run there, no chat host, a client missing the capability) now reads
  "This isn't available in this chat.", since updating doesn't fix it.
- A task Orca lost track of is "no recent update" everywhere; after a count it
  reads "2 agents with no recent update" instead of a second name.
- The skills menu announces the same sentence it shows, including in SSH chats.
- The row for messages held behind a previous agent reads "{{agent}} from before
  may still be running. Your messages will send once it stops."

* fix(native-chat): a chat whose host can't run it says its history didn't load

A history read refused as unsupported with a named reason left the error pane
saying only "This isn't available in this chat.", which never said the chat
failed to load and named nothing the reader asked for. A read now says "This
chat's history couldn't be loaded."; other writes keep the shorter sentence.
