perf(logging): reduce logging overhead in hot paths

- Remove dead debug lambda in PUTFileJob::start() that constructed a
  temporary QLoggingCategory on every upload progress tick. The signal
  is already connected to the proper handler on the next line.
- Add QtInfoMsg default to 3 Q_LOGGING_CATEGORY declarations that were
  missing it, preventing debug-level output from being active by default.
- Remove tr() and QString::number() allocations from a qCDebug call in
  usermodel.cpp quota update path.
