In `@lib/data/provider/pve.dart`:
- Around line 59-65: The provider's build method (PveState build(Spi spiParam))
wrongly uses ref.read(serverProvider(spiParam.id)) and immediately returns a
PveErr when serverState.client == null, preventing rebuild when genClient()
later sets client; change ref.read(...) to
ref.watch(serverProvider(spiParam.id)) so the provider will rebuild when
ServerState.client becomes available and replace the immediate error return with
a non-error/loading PveState (or defer error only for real failures) so a
transient null SSH client doesn't become a permanent PVE error.

In `@lib/view/page/pve.dart`:
- Around line 142-148: Replace the hardcoded English strings in
_buildLoading(PveLoadingStep step) (the message variable for
PveLoadingStep.forwarding, PveLoadingStep.loggingIn,
PveLoadingStep.fetchingData, and the default) with localized strings from the
app l10n (e.g., use context.l10n or AppLocalizations.of(context).<key>); if the
keys do not yet exist, add appropriate keys to the ARB/localization resource
files (forwarding, loggingIn, fetchingData, connecting) and regenerate
localization, then reference those keys in _buildLoading so the UI uses
translated messages instead of hardcoded text.

Outside diff comments:
In `@lib/data/provider/pve.dart`:
- Line 11: Remove the unused locale import and eliminate the dead assignment to
newUrl: delete the import of
'package:server_box/core/extension/context/locale.dart' near the top of
lib/data/provider/pve.dart, and in the block where newUrl is assigned
(previously lines ~136-138) either remove the newUrl variable/assignment
entirely or refactor to actually use newUrl in the subsequent logic; ensure no
other symbols in pve.dart reference that import or variable and re-run flutter
analyze to confirm warnings are cleared.

In `@lib/view/page/pve.dart`:
- Around line 72-79: The retry button currently only calls _notifier.list(),
which is ineffective when the PVE bootstrap/login/connection hasn't completed;
change the handler in the Btn.icon onTap to invoke the PVE bootstrap/reconnect
routine (the method that initiates connection/login/bootstrap on the notifier —
e.g., _notifier.bootstrap() or whatever method triggers the full bootstrap flow)
instead of just _notifier.list(), and still call _initRefreshTimer() afterwards
so the refresh timer is reinitialized; reference the Btn.icon onTap,
_notifier.list(), _initRefreshTimer(), and the notifier's bootstrap/connect
method when making the change.
