v0.0.17: fix /r reply in TUI, /p shortcut, /eth, /unalias

TUI fixes:
- /r and /reply now work: tracks last_dm_peer from received messages
- /r switches peer to last DM sender, then type normally
- /p @alias works as shortcut for /peer @alias
- /eth shows Ethereum address in TUI
- /unalias removes your alias

Web fixes:
- /p @alias and /peer @alias resolve and set peer
- /r and /reply work (switch to last DM sender)
- /unalias removes alias
- /admin-unalias <alias> <password> for admin removal
- File download now shows as clickable link (not auto-download)

Server:
- POST /v1/alias/unregister — remove own alias
- POST /v1/alias/admin-remove — admin removes any alias
- WARZONE_ADMIN_PASSWORD env var (default: "admin")
