Release v1.5.0: log redesign + iOS 17 baseline

[tashda]

Summary

Visual + functional overhaul of the Activity log surface, plus iOS 17 baseline and a small toolbar polish.

• Activity log + log detail + Recent Events card + Group compact card all share one aesthetic now: device image (or group icon) as the leading avatar, category as a bottom-trailing corner badge, severity tints the row title, no chevrons. Log detail uses a stacked title + timestamp subtitle in the nav bar (Phone/Messages pattern).
• Z2M attribution: bridge/response/device/... and <device>/action-style publishes now resolve to the real device/group (via payload.data.id / data.to / data.friendly_name, falling back to scanning payload.error for a known device name when responses fail). Fixed the payload extractor that was truncating JSON at embedded single quotes ('office_remote', didn't).
• Cleaner state changes: dropped elapsed, dropped empty-string transitions, formatted filter_age / device_age as durations (4 mo instead of 177242), removed the duplicate full-payload snapshot under state-change diffs, and scoped the device-state card to actual device exposes so bridge errors show only the hero card.
• iOS 17 baseline: deployment target lowered from iOS 18 to 17. This also clears the iOS 26 toolbar/tab-bar gap on the Logs page.
• Toolbar polish: bulk-OTA ProgressView no longer renders smaller than the glyph it replaces.

Test plan

• Activity log: device images render without circle clipping; group rows show member-avatar icon; bridge OTA responses (success and error) attribute to the device, not bridge/response/...; remote button presses produce one row, not three
• Log detail: title + timestamp stacked in nav bar; long error strings wrap fully; bridge error logs show only the hero card (no empty exposes section); state-change logs show only the diff (no duplicate payload snapshot); filter_age reads as 4 mo not 177242
• Home page Recent Events: matches activity row aesthetic
• Group compact card matches device compact card structure
• Bulk OTA: spinner in toolbar is the same size as the up-arrow glyph
• App still builds and launches on iOS 17 simulator
