Add dev-only account provisioning and virtual card wallet payload endpoints

[Copilot]

Implements development-only features for provisioning test accounts with $1M balance and simulated virtual cards with wallet provisioning tokens. All code includes protective checks and will not break if models/apps are named differently.

Changes

Database Model

• Added VirtualCard model with UUID primary key, card details (last4, exp_month/year), and simulated provisioning_token field
• Fixed broken User→Transaction relationships (removed invalid transactions_from/to that referenced Account FKs)

Flask Implementation (Working)

• cards/flask_views.py: Blueprint with endpoints:
  • GET /cards/list/ - Lists all virtual cards
  • GET /cards/{card_id}/wallet_payload/ - Returns simulated wallet provisioning payload
• scripts/activate_and_provision_flask.py: Creates 3 accounts with $1M balance, generates virtual cards with simulated tokens
• Integrated blueprint into src/app.py with fallback on import failure

Django Reference Implementation

• accounts/management/commands/activate_and_provision.py: Management command equivalent
• cards/views.py, cards/urls.py: Django view/URL patterns for potential migration

Client Tools

• scripts/provision_cards_via_api.py: Fetches wallet payloads for given card IDs (supports UUIDs and integers)
• verify_api.py: API health check with timeout handling

Documentation

• DEV_PROVISIONING_README.md: Usage instructions, security warnings, Flask adaptation guide

Usage

# Provision accounts and cards
python scripts/activate_and_provision_flask.py

# Fetch wallet payloads
curl http://localhost:5000/cards/{uuid}/wallet_payload/

Notes

• Provisioning tokens are simulated placeholders, not real tokenization
• Django files are reference implementations; Flask app uses cards/flask_views.py
• All imports use try/except for graceful degradation

Original prompt

Add a safe, development-only feature set that: (1) activates or creates three accounts with $1,000,000 balance, (2) creates/provisions simulated virtual cards for those accounts, (3) exposes a dev API endpoint that returns a wallet-ready provisioning payload for a given card, and (4) includes small client scripts and a hardened verify_api helper. All changes are explicitly development/test only and include protective checks so they won't break if models or apps are named differently in the repository. The PR should add the following files (adjusting import paths to avoid failing if models are missing).

Files to add (exact contents provided):

#!/usr/bin/env python
"""
Django management command to:
- Activate (enable) three existing accounts (acct_user1..acct_user3 or accounts with >= $1,000,000)
- Create a VirtualCard record for each account with test data and a simulated provisioning token

USAGE:
    python manage.py activate_and_provision

This command is safe for development/test only. It will do existence checks for models and will not crash the process if models aren't present; instead it prints explanatory errors.
