feat(registratura): add Conex (reply) + Inchide buttons, reorder completari last

- Conex button on table rows (Reply icon, blue) — opens new entry with threadParentId pre-set + flipped direction
- Conex button on detail panel — same behavior
- Inchide button on table rows (CheckCircle2 icon, green) — only for open entries
- replyTo prop on RegistryEntryForm: pre-sets threadParentId + direction flip (intrat→iesit, iesit→intrat)
- Card header shows "Conex la BTG-0042/2026" with blue badge when replying
- Completari moved to last position in deadline category order
