v1.6.58: defer database resolution during package discovery

[roncodes]

Summary

• resolve UserDeletionService only when fleetbase:user-delete executes
• prevent Composer/Laravel package discovery from opening MySQL during image builds
• bump Core API to v1.6.58 and add current release notes

Regression coverage

• verifies the command resolves while the database-backed service binding throws
• preserves dry-run, validation, confirmation, execution, and rollback behavior

Validation

• vendor/bin/pest tests/Unit/Console/DeleteUserCommandTest.php (8 passed, 26 assertions)
• composer test:unit (1,416 passed, 9,941 assertions)
• composer test:lint (0 files need changes)
• composer test:date-drift
• root API php artisan package:discover --ansi with DB_HOST=127.0.0.1 DB_PORT=1

This fixes the v0.7.54 release image regression where composer dumpautoload failed with a MySQL connection-refused error before database services were available.
