- footer read 'v0.1' forever; it's injected from package.json at build
time now
- region picker shows 'Failed to load' instead of an eternal Loading
when /iatas errors
- selecting text in a modal and releasing over the backdrop no longer
closes it (close requires the press to start on the backdrop)
- Escape in a dropdown inside the mobile filter sheet closes just the
dropdown, not the whole sheet
- Shift+Tab right after a modal opens wraps to the last control instead
of escaping the focus trap
- formatCount rolls 999,999 over to 1M instead of printing 1000k
- TABS list moved to lib/constants so AppShell only exports components
