feat(desktop): diagnostic + manual retry for legacy key migration

The 0.18.1 fix relied on an existing-device + present-stronghold-key match.
That fails for users who:
  - had multiple device registrations and only retain the latest device's
    private key in the local vault
  - had a vault wipe / fresh OS install at some point
  - have device rows that vanished server-side but keys still locally

Migration now scans conversation_keys for distinct un-migrated
recipient_device_ids visible to the user (RLS-filtered) and probes the
stronghold for each, regardless of whether the server still lists that
device. Result struct surfaces attempted/migrated/noKey/decryptFail/rpcFail
counters; SecurityCenter shows them via a new "Migration erneut ausführen"
button so users can self-diagnose without DevTools.

Also adds [crypto-migration] console.info breadcrumbs at every decision
point so a single F12 shows what happened.
