Add payouts, PDF attestations, sub-accounts, and webhook improvements

Payout system:
- Create Payout entity (stripePayoutId, status, amount, currency, destination, arrivalDate)
- Webhook handles payout.created/updated/paid/failed/canceled with email notification
- Payout list in /mon-compte virements tab with status badges
- PDF attestation on paid payouts with email attachment

PDF attestation:
- dompdf with DejaVu Sans font, yellow-orange gradient background
- Orange centered title bar, E-Cosplay logo, emitter/beneficiary info blocks
- QR code linking to /attestation/check/{payoutId} for authenticity verification
- Public verification page: shows payout details if valid, error if altered
- Legal disclaimer and CGV reference
- Button visible only when status is paid, opens in new tab

Sub-accounts:
- Add parentOrganizer (self-referencing ManyToOne) and subAccountPermissions (JSON) to User
- Permissions: scanner (validate tickets), events (CRUD), tickets (free invitations)
- Create sub-account with random password, send email with credentials
- Edit page with name/email/permissions checkboxes
- Delete with confirmation
- hasPermission() helper method

Account improvements:
- Block entire page for unapproved organizers with validation pending message
- Display stripeStatus in Stripe Connect banners
- Remove test payout button

Webhook v2 Connect events:
- v2.core.account.created/updated/closed → update stripeStatus
- capability_status_updated → sync charges/payouts enabled from capabilities
- PayoutPdfService for reusable PDF generation

Migrations: stripeStatus, Payout table, sub-account fields, drop pdfPath
