Export save turns the whole save into one code (gzip + base64url
behind a DEADHEAD1. prefix) to copy or share as a file; Import save
takes a pasted code or a file, migrates and validates it, and replaces
the company after confirmation. A bad code is refused and changes
nothing. These replace the backup code. Debug info now gives the save
id, save version and storage type.

The engine derives the notification schedule from the save after every
saved change (arrivals, rest ending, upgrades; same-minute events
combined) and replaces the platform's schedule. Capacitor
LocalNotifications on iOS/Android, a no-op on the web. Permission is
asked after the deal; Settings has an On/Off toggle.
