fix: surface schema load errors and normalize update_server inputs (#41)

- registry.py: replace bare `except Exception: pass` with specific
  exception handling and a warning log, so corrupted schema.json files
  are visible instead of silently disappearing from workflow list
- services.py: apply the same input normalization in update_server as
  add_server (strip whitespace, coerce types, apply fallback defaults)
  to prevent dirty data from entering config
