peter f92cd9017f fix: the diagnostics tab keeps its focus, its level and its consent
Deep-review round 1 of E22.

- After a 429 the stream sent one POST per new event while a full batch
  waited; it now stays quiet for 15 s. Past the queue cap the oldest
  events go, as the comment always said, a refused batch included.
- A batch refused after the level was lowered came back into the queue
  of a later consent in the same tab; each consent is its own session.
- A `me` fetch that left before a level or preference change could put the
  old value back for up to a minute. `updateMeCache` writes the cache and
  cancels that fetch; usePref goes through it too.
- The consent box's buttons and "revert now" took the focus with them to
  <body>; it returns to the level picker. Watched until the button is
  gone — in Chrome the saved level arrives in two renders, and a one-shot
  check spent itself on the first (jsdom never showed it).
- The countdown line is no longer a live region re-read every minute.
- "Saját napló" rows were keyed by index on a newest-first list, so every
  new event remounted every row and dropped the focus off a row button.

/** Write a change the SERVER already has (or is about to) into the `me` cache — and cancel a `me`
* fetch still in flight. That fetch may have left before the change was saved (BootGate's 60 s poll,
* a refetch on window focus); answering after the write, it would put the old value back and hold it
* until the next poll. Cancelling reverts the query to its latest state, which is this write:
* react-query takes a manual write as the state to revert to. */

// The signed-in account, read from the qk.me() query cache. BootGate owns the FETCHING query (gated on
// setup state) and App renders modules only once it has resolved to a real user — so anywhere inside the
// authenticated module tree the cache is always populated. `enabled:false` makes this a passive
// observer (no second fetch, which could 503 in setup mode) that still re-renders when the cache
// updates (login, the 60s refetch, a Google-link round-trip). Lets modules read `me` from a hook
// instead of having it prop-drilled through App.
