Migrate all primary keys + foreign keys to UUID (HasUuids trait)

Per user request: switch from auto-increment IDs to UUID v4 across all
models.

Models — added HasUuids trait:
- User, Cluster, Server, Site, Backup, TeamMember, Invitation,
  SecurityEvent, Certificate, Activity, Cron.

Migrations — $table->id() → $table->uuid('id')->primary(),
$table->foreignId(...) → $table->foreignUuid(...) across stock laravel
users/sessions/jobs migrations + all 10 domain migrations.

Routes: sites/{site} (and any other implicit route-model binding) keeps
working since Laravel resolves by primary key as a string. Tested:
clicking a site row → URL now /sites/019e800c-520a-7022-badd-2ef9d9ed5c61.

Re-seeded: 6 users, 87 sites, 6 servers, 128 security events, 30
activities, 102 backups, 47 crons, 87 certs, 5 team members, 3 invites.

Full Pest regression: 47/47 green. Browser-verified login + sites
index + site details + WP/PHP/Files tabs with template-exact chrome.
