slipway 1.0.0-alpha3

The dashboard is now Slipway's own web UI, inside the admin theme.

• Workflow matrix: Code, Database and Files across every environment. Drag a Code cell onto a later environment to deploy it, or a Database or Files cell onto an earlier one to copy it down. Live log, stalled sequences, job steps and audit history, plus Databases (snapshots and restore), Cron (schedules) and Releases tabs.
• The browser only talks to Drupal. A JSON API checks every operation against the same permissions as the operation forms, requires the CSRF header token, and refuses production changes unless the environment name is typed. Controls are hidden where the user lacks permission. Slipway's console is never exposed.
• Releases deploy by image digest, not by a git ref several builds may share.
• New Drush commands: slipway:releases, slipway:snapshots, slipway:history, slipway:stalled, slipway:schedules, slipway:restore, slipway:rollback, slipway:cancel, slipway:resume.
• Fixed: forms failed to unserialize on PHP < 8.4 because of readonly injected properties.

Requires Slipway with API v1, including GET /api/schedules.
