Custom schema rules correctly override default decorators

• schema-generator: prevent default decorators from leaking into custom schema rules
  (66e0a5ce)

loadRules() was using deepmerge without custom merge strategies, which caused two issues:

1. decorators array format: default decorators were concatenated with user-defined ones instead of being replaced (e.g.
   [@column(), @decimal()] instead of just [@decimal()])
2. Deprecated decorator string format: the default decorators array took precedence over the user's decorator string,
   silently ignoring it

Custom type and column rules now correctly replace the defaults.
