fix(wavelog): a 200 is not an acceptance

WaveLogApi decided an upload had succeeded from the HTTP status alone. Wavelog validates
after responding, so a rejected QSO comes back as 200 with `{"status":"failed","reason":
"..."}` - and the uploader then called markUploaded and dropped it from the queue. The
contact was lost and the operator was told the upload succeeded.

Response shapes are transcribed from the Wavelog API reference, not guessed: success is
`status: success` or `successful`, a duplicate is `status: dupe` with a 200, failures are
`status: failed` with `reason` or `status: error` with `message`.

WavelogResponse reads the body. Four outcomes: accepted and duplicate both clear the
queue entry, because the log holds the QSO either way; rejected keeps it and surfaces the
server's own explanation; and a status field we cannot recognise also keeps it, since
costing a retry beats losing a contact. Parsed as text rather than with JSONObject because
org.json is compileOnly in core:domain and a JVM test would otherwise assert against a
stub. Whitespace around separators is collapsed before matching - a first attempt listed
spacings and missed `{ "status" : "failed" }`, which a probe caught.

Two other things in the same area.

The ten-minute auto-upload loop is gone. It retried the queue in the background with no
way to tell the operator anything: a grid mismatch was swallowed by an empty if block and
every other failure retried silently forever. A QSO that cannot be uploaded now waits for
a manual upload from settings, where the result is actually shown.

The upload path no longer builds user-facing text in Kotlin. UploadOutcome carried a
pre-formatted Chinese string, so the message ignored the device language whatever the
locale files said. It now reports a Reason the view model maps to resources, which needed
a format-argument overload on IShowToast to get a count into a localised message.
