Add 1Password Encrypted Vault Backup App

[ag-rdoucette]

Description

This pull request introduces a new web application for securely backing up and restoring 1Password vaults using the 1Password JS SDK and CLI. The app encrypts vault data with Argon2 and AES-256-CBC.

Key features include:

• Backup: Connects to a 1Password account via a service account token, lists vaults, encrypts selected or all vaults with a user-provided passcode, and generates a downloadable backup.1pbackup file. Encryption keys can be saved to a 1Password vault or downloaded.
• Restore: Uploads the encrypted backup file, uses the passcode and system key to decrypt, and restores vaults to a destination account, creating new vaults with "(Restored)" appended to names.
• Security: Implements HTTPS with a self-signed certificate, HMAC-SHA256 for integrity, p-limit for API concurrency control, and retry logic for rate limits.
• CLI Integration: Uses 1Password CLI for vault creation (not supported by SDK).
• Dockerized Setup: Runs via Docker Compose for easy deployment.

The app addresses secure vault backup/restore needs but has limitations: passkeys and archived items are not supported, and concurrency is fixed (2 vaults, 1 item at a time). The README provides detailed setup, usage, and troubleshooting instructions.

You can match these against the actual ItemCategory type and this goes for everywhere.

Reviewing....

[scottisloud]

should add data-1p-ignore prop to form elements to avoid 1Password attempting to save values put into fields.

No major changes beyond those already requested. I know you've got some additions to make so not approving officially.
