fix: differentiate Conex (linkedEntryIds) vs Inchide (threadParentId) semantics

- Conex button now adds to linkedEntryIds (for clarificari/solicitari)
  instead of setting threadParentId
- Inchide button sets threadParentId (direct reply) + auto-closes parent
- Fix Sterge button persistence bug: threadParentId now saves as empty
  string instead of undefined (which was stripped in JSON serialization)
- Card headers: "Conex cu X" (amber) vs "Raspuns la X" (blue + green)
- Add conexTo prop to RegistryEntryForm for linked entry pre-fill
