NIP‑17/44: XChaCha20 v2 gift wraps, DM kind=14, receipts + UI fixes (#506)

Browse Source 
* NIP-17/44: adopt NIP-44 v2 (XChaCha20-Poly1305, v2: base64url), switch rumor kind to 14, randomize BIP-340 aux; add XChaCha20Poly1305Compat and wire-up

* Nostr DMs: ensure delivered/read acks are sent even without Noise key mapping by falling back to direct Nostr (geohash-style) acks to sender pubkey

* NIP-44 v2 decrypt: try both Y parities for x-only sender pubkeys (even then odd) to fix unwrap authentication failures

* Tests: add NIP-44 v2 ACK round-trip tests (delivered/read) using bitchat1 embedding and gift-wrap decrypt path

* UI: fix DM autoscroll IDs by using dm:<peer>|<id> for private chat item IDs and preserve anchors, ensuring scrollTo targets exist when opening/switching/new messages

* UI: fix string interpolation in DM/geohash context keys (remove escaped interpolation) to resolve 'unused ch' warnings and ensure proper IDs

* UI: MeshPeerList shows transport state icon: radio for mesh-connected, purple globe for mutual favorite/Nostr; fallback dim person for others
