docs(airgapped): inline restore script in community-to-airgapped guide

[akshat5302]

Summary

• Replace the restore-airgapped.sh download URL in the Community → Airgapped migration guide with the full script content inlined in the doc, so users in airgapped environments can create the script locally without internet access
• Update the restore steps accordingly (create script → chmod → move backup → run)

Test plan

• pnpm check:format passes (Prettier verified locally)
• VitePress build renders the embedded script code block correctly

🧙 Built with WOZCODE

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

The migration guide replaces the downloaded restore script with an inline Bash script. The script validates paths, restores backup archives, maps data directories to compose volumes, and fixes ownership. The procedure now includes script creation, authorization, backup transfer, and execution.

Changes

Airgapped restore workflow

Layer / File(s)	Summary
Embedded restore script docs/self-hosting/manage/community-to-airgapped.md	The guide adds a Bash script that validates the backup and installation paths, checks the compose service state, extracts backup archives, renames restored directories, selects the compose command, and fixes ownership.
Restore execution procedure docs/self-hosting/manage/community-to-airgapped.md	The steps now cover creating the script, making it executable, moving the backup folder to the airgapped server, and running the script with the backup path.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟠 High · up to d6c17

The new airgapped restore workflow runs transferred backup archives with elevated privileges and writes directly into live application data without sufficient archive validation or safe staging, while several documented checks can permit partial restores, service conflicts, or unusable file ownership. This creates a high-impact security and availability risk, so the PR should not merge until these issues are fixed.

Inline comments:
In `@docs/self-hosting/manage/community-to-airgapped.md`:
- Around line 97-99: Strengthen the backup validation before any rm -rf or mv
operations: require all expected archives or recognized archive members, rather
than accepting any .tar.gz. Stage and validate the complete restore first,
ensuring every target is present, then commit the replacement only after
validation succeeds; reject unrelated or partial backups without modifying the
existing installation.
- Line 80: Update the BACKUP_FOLDER assignment to use an empty fallback when no
positional argument is provided, preserving the subsequent prompt and
$PWD/backup default behavior under set -u.
- Line 202: Update the restore instructions around chown to preserve the
invoking user’s UID and GID instead of using values set to 0 by the sudo
invocation, ensuring restored bind-mounted data remains writable by non-root
Compose services; alternatively derive the ownership from the target Compose
configuration.
- Line 133: Update the dockerServiceStatus assignment to tolerate no matching
Compose project under set -euo pipefail by returning an empty status, and
recognize running statuses such as running(1) by checking for a running token
before extracting the status. Preserve the existing downstream handling for
non-running or absent projects.
- Line 155: Update the restore flow around the tar extraction command to stage
each archive in its own empty temporary directory before privileged extraction.
Validate and reject symlink or unsafe path members, then move only validated
contents into $AIRGAPPED_INSTALL_PATH/data, preserving isolation between
transferred archives.
