Fixes#779
## Changes
Auto-generate WOODPECKER_TOKEN during disinto init by automating the Forgejo OAuth2 login flow after the compose stack starts. Adds generate_woodpecker_token() function that: logs into Forgejo web UI, drives the OAuth2 authorize/consent flow, completes the Woodpecker callback to get a session token, then creates a persistent personal access token via Woodpecker API. Saves to .env so activate_woodpecker_repo() can use it immediately. Failures are non-fatal (guarded with || true).
