fix(startup): Firefox no longer hangs on "Heating up" after login (#303)

initClient awaited navigator.storage.persist() before creating the client.
Chromium and WebKit answer at once, but Firefox shows a permission prompt
and leaves the promise pending until it's answered, so the app sat on
"Heating up" (no sync, no crypto, no IndexedDB) for every Firefox user who
didn't notice the prompt.

The request is still made (KE-1 only needs that), but startup waits at
most 1.5 s for the answer. The comment claiming persist() never prompts
is corrected.

Verified in Playwright Firefox with the prompt left unanswered
(persist() still pending): before, still "Heating up" after 20 s; now the
room list after 12 s.

Fixes #303
