feat: prevent actions when identification methods are disabled

Add comprehensive validation for disabled identification methods:
- Check method status in canSignerActInOrder to centralize validation
- Hide menu actions (customize message, request signature, send reminder)
  for signers with disabled methods
- Add hasSignersWithDisabledMethods computed property
- Hide "Setup signature positions" and "Request signatures" buttons
  when any signer has a disabled method
- Show warning message when disabled methods are detected
- Always show signer's method in edit dialog even if disabled
- Pass disabled prop to IdentifySigner component

This ensures users cannot proceed with signature requests until all
signers have valid identification methods.
