Favorites: remove npub resend tracking and nickname-based key migration; rely on Noise key as identity

* Fix emote targeting and grammar; add tests

Prevent 'system' mis-target via peerID-derived display name in actions sheet. Correct /hug and /slap usage/error grammar by passing base command name. Improve geohash nickname resolution to match displayName with #suffix. Add CommandProcessor tests.

* Geohash ordering: strict in-order inserts and timestamp clamp

Use channel-aware late-insert threshold with 0s for geohash to keep strict chronological order. Clamp future Nostr event timestamps to 'now' to avoid future-dated items skewing order in geohash timelines.

* Trim trailing/leading spaces in geohash nicknames and tag emission

Sanitize Nostr 'n' tag values on ingest and emit by trimming whitespace/newlines to prevent trailing spaces in displayed usernames. Local nickname is already trimmed on focus loss and submit.
