feat(migrations): enable recursive discovery in subdirectories

[usernane]

Summary

Enable recursive discovery of migrations and seeders in subdirectories for all CLI migration commands.

Motivation

Organizing migrations by domain in subdirectories (e.g. Database/Migrations/Master/, Database/Migrations/Lms/) is silently ignored because discoverFromPath() is called without $recursive = true. Fixes #317.

Changes

• Pass true for the $recursive parameter in discoverFromPath() calls across all 5 migration commands:
  • RunMigrationsCommandNew
  • FreshMigrationsCommand
  • RollbackMigrationsCommand
  • DryRunMigrationsCommand
  • MigrationsStatusCommand
• Move legacy broken test fixtures (MultiErr, EmptyRunner, NoConn) from App/Database/Migrations/ to tests/fixtures/Database/Migrations/
• Add RecursiveMigrationDiscoveryTest with 9 test cases covering all commands

How to Test / Verify

Unit tests: run phpunit --testsuite "CLI Tests" --filter RecursiveMigrationDiscoveryTest

All 9 tests verify that migrations/seeders placed in subdirectories are discovered and executed correctly.

Breaking Changes and Migration Steps

None. Existing top-level migrations continue to work. Subdirectories that were previously ignored will now be scanned.
