fix: replace removed brctl download with open -g; add -f to mackup restore

brctl download was removed in macOS Sonoma — the remaining subcommands are
diagnose/log/dump/status/accounts/quota/monitor. Replace the dead call with
a find loop that uses 'open -g <real-path>' to request per-file iCloud
download from the daemon, followed by a 1-second settle pause and the
existing .icloud stub deletion.

Also add -f to mackup restore for consistency with the backup call.
