connectWithPassword() had no try/catch around firebaseFactory(), unlike
connectWithGoogle() right next to it. A thrown FirebaseAuthError (wrong
password, 400 from identitytoolkit) escaped uncaught out of the button's
async onPressed, so _busy/_status never updated and the screen sat on
"Signing in..." forever with no error shown -- reproduced live via the
browser console (confirmed "Uncaught Error" immediately after the 400,
not a hung Future).
Also reports real progress stages ("Saving account...", "Signing in to
Firebase...") instead of one static string, clears the bad password on a
confirmed rejection (previously only the null-client branch did, letting a
background sync tick keep retrying it), and surfaces the actual failure
reason in the status text instead of a generic "rejected" message.

lyricanki's Linux desktop cannot use google_sign_in (no Linux
implementation) and its loopback replacement is dark until a Desktop OAuth
client exists. Hiding the button there makes the screen silently offer less
on one platform, which reads as a bug.
googleUnavailableReason renders a *disabled* button plus the reason. That is
not the "control that can never succeed" trap: the trap is a live-looking
button that reports a fake cancellation, and a null onPressed cannot be
tapped at all. Null stays the default, so every existing host is unchanged.

Two traps this hit, both invisible to a line count:
- _FakePersistence is declared *after* main(), so a naive cut at the last
brace dropped it; sync_revisions_persistence_test.dart failed to load
until it was carried across. Audited every other split file for trailing
top-level declarations — this was the only one.
- Copying the preamble into each sibling left helpers the sibling never
uses. `dart analyze` flagged 12; all removed rather than left as dead
code, and the analyzer is now clean.
crdt_sync_dart 280 passed, sync_settings_ui 29 passed, github_device_auth
analyze clean — all matching a clean HEAD worktree.
