Auto-submit iOS builds for App Store review via fastlane

Adds a fastlane lane and an EAS Workflow custom job that runs after
submit_ios. Picks up the latest TestFlight build, waits for Apple
processing, and submits for review with auto-release on approval.

Uses ASC_KEY_ID, ASC_ISSUER_ID, ASC_KEY_P8 secrets from the EAS
production environment.
