Add NIP-17 gift-wrapped DMs, follow-from-menu, fix new conversation crash

DMs now send via NIP-17 (kind 1059 gift-wrap) with self-copy for sent
messages. Receive supports both NIP-17 and legacy NIP-04 for backward
compat. Protocol indicator shown in conversation list and compose footer.

Note card context menu (⋯) now includes follow/unfollow option so users
can follow authors directly from the feed without visiting their profile.

Fix crash (black screen) when starting a new DM conversation — empty
event array caused undefined access on lastEvent.
