* test(deeplink): pin terminal-failure replay and referendum path matching
These fail on main: a link that fails for good is kept as pending and
replayed on every launch, and /open/governance matches the referendum
handler.
* fix(deeplink): drop a pending link once it fails for good
RootDeepLinkHandler cleared the persisted pending link only on success or
when no handler matched. A link that reached a handler and failed with a
DeepLinkHandlingException stayed in preferences and was replayed on
every launch. Clear it on terminal handling failures in both the fresh
and pending paths; this also recovers installs already stuck on update.
Other failures keep the link pending for a retry.
* fix(deeplink): match the referendum path exactly
ReferendumDeepLinkHandler matched any path starting with /open/gov, so
the governance banner link /open/governance went to the referendum
screen and failed with ReferendumIsNotSpecified.
Add pezpallet_* type paths to SiVoteTypeMapping so ConvictionVoting
vote encoding works on Pezkuwi chains. Set Pezkuwi relay as preferred
default chain for governance and crowdloan screens.
