Enable Finder Wi-Fi sync from the device view

[AJV20]

Summary

• Add a USB-only Enable Wi-Fi action that maps to Finder's "Show this iPhone when on Wi-Fi" setting via pymobiledevice3 lockdown wifi-connections --state on
• Retry after pairing/trust if needed, but do not treat pairing alone as successful Wi-Fi enablement
• Treat pymobiledevice3 lockdown stderr error markers such as Device not found as failures even when the CLI exits 0
• Add a Backup quick action on the Device page, including a linear loading bar and sanitized Backing up progress copy
• Correct current iPhone18,* model mappings so iPhone18,2 displays as iPhone 17 Pro Max
• Invalidate device discovery caches and show guidance to unplug, keep the device unlocked, and rescan
• Bump local app bundle version to 1.0.11

Verification

• Scripts/regression/run.py
• swift build
• swift build -c release
• bash Scripts/build.sh
• Installed /Applications/Phosphor.app and launched version 1.0.11 with a visible window

Merged into main - this closes #45. The wifi-connections change is the right fix: the old path reported success after pairing alone, which never flips Finder's "Show this iPhone when on Wi-Fi" flag. Resolved the BackupViewModel overlap with #33 by keeping the operation-ID progress guard and routing through this PR's updateBackupProgress helper.
