Support bot: swap Code Week 4 All participation codes on scoped events

[bernardhanna]

Summary

• Add support:event-participation-code-update to preview and apply participation code swaps on events scoped by year/month
• Parse requests like Rosa Montalbano's email (change cw25-E6CDg → cw26-wNc6o for June 2026 activities)
• Wire support bot triage to run a dry-run first, then apply on email APPROVE

Bot flow

1. Email: "change the code cw25-E6CDg with cw26-wNc6o for activities registered in June 2026"
2. Bot dry-runs and sends approval email listing matched events
3. Reply APPROVE to update only those scoped events

Manual CLI (same logic as tinker, no tinker needed)

# 1. Preview
php artisan support:event-participation-code-update cw25-E6CDg cw26-wNc6o --year=2026 --month=6 --dry-run --json

# 2. Apply
php artisan support:event-participation-code-update cw25-E6CDg cw26-wNc6o --year=2026 --month=6 --json

Test plan

• Unit tests for parser, service, and artisan allowlist
• Deploy + run dry-run on prod for Rosa's case before applying
• Forward a test email to support bot and confirm APPROVE flow
