feat: release TypeType 1.7.0

[Priveetee]

Summary

• release TypeType 1.7.0 across Frontend, Server, Token and Downloader
• update TypeType-Player to MSE 0.1.56
• add account portability imports and exports with progress and diagnostics
• add the English/French localization catalog and Weblate workflow
• improve SABR startup, progressive VOD delivery, seeks and playback resume
• add the subscription-group membership API and the TypeType management preview
• preserve downloader artifact metadata and serialize remote YouTube login input
• publish the 1.7.0 release notes
• advance every component pin to its reviewed main revision

Production behavior

• saved playback positions are restored before SABR startup
• progressive VOD media and reused bootstrap preparation reduce startup work
• MSE 0.1.56 keeps buffered seeks and source transitions stable
• the web application exposes the import workspace and localization surfaces
• contributors can translate apps/web/messages/*.json through Weblate
• subscription-group membership supports bounded atomic batch updates
• downloader artifacts retain response metadata such as Content-Length
• remote YouTube login input preserves pointer press/release ordering

Deployment requirements

No configuration change or manual database migration is required for this release. Server creates the subscription-group tables through normal schema initialization.

Deploy only after the four component stable images and their multi-architecture manifests are published for 1.7.0.

The generic one-shot installer remains available at scripts/install-stack.sh; it defaults to main, supports --ref v1.7.0, preserves existing .env values and keeps the rollback files created during an update.
