fix: SMB share enumeration, BrowseView polish, sign out, Login branding
- Fix "Bad Network Name": BrowseView at root "/" for SMB now calls
listShares() instead of listDirectory with empty share name.
SMBClient.listShares() filters IPC/admin/hidden ($) shares.
- Add listShares() to NASTransferProtocol; implement in SMB (filters
ipc/special/$-suffix) and SFTP (returns []).
- BrowseView: premium error state (wifi.exclamationmark icon + Retry
button with ScaleButtonStyle), empty state, safeAreaInset bottom bar
replacing toolbar bottomBar (shows current path chip + compact Select
button), proper disabled state for root selection on SMB.
- FolderRow: replace hardcoded .white with AppTheme.inkInverse for dark
mode correctness; use folder.fill icon; ScaleButtonStyle for tap feedback.
- LoginView: larger logo (80pt), bolder "Kisani" wordmark (32pt bold),
tagline, staggered spring entrance animations (0.08-0.36s delay).
- SettingsView: Sign Out button in ACCOUNT section with
confirmationDialog (destructive, clears connection + resets session).
- ConnectionStore: signOut() resets isSessionActive, onboardingPhotoShown,
and clears savedConnection (triggers Keychain delete).
