fix: add NIP-10 and NIP-22 support to chat command reconstructor

The edit button in chat windows now correctly reconstructs commands for:
- NIP-10 threads: chat nevent1... format
- NIP-22 comments: chat nevent1... for event pointers, chat naddr1... for
  address pointers (e.g., articles)

Previously only NIP-29 (groups) and NIP-53 (live activities) were supported.
