fix: keep lead invite command aliases (#406)

## Sentry issue
- https://whisper-money.sentry.io/issues/PHP-LARAVEL-1H

## Root cause
Production invoked old/typoed Artisan command names (`leads:send-invite`
/ `leads:send-invites`) after the command was named
`leads:send-invitations`, causing Symfony CommandNotFoundException
before command logic ran.

## Fix
- Add compatibility aliases for previous invite command names.
- Add regression coverage that both aliases execute successfully.

## Verification
- `vendor/bin/pint --dirty --format agent`
- `php artisan test --compact
