Bump version to 0.1.7 — Windows playtest fixes

Critical:
- NWC wallet now stored per-account (wrystr_nwc_<pubkey>); switching
  accounts loads the correct wallet automatically
- Clear NDK signer before account switch to prevent race where old
  account could sign outgoing events
- LoginModal: add "New account" tab to create a fresh keypair inline
  (same flow as onboarding, with nsec copy + confirmation checkbox)
- ThreadView: add like + zap action row to the root note (was missing)

UX:
- Zap button now conditional on lud16/lud06 (NoteCard, ProfileView,
  RootNote) — no zap button shown for profiles without Lightning
- Remove "200 notes" counter from sidebar footer
- AccountSwitcher: larger active account avatar (w-8), name more
  prominent; sign-out/remove moved into dropdown only

Quick wins:
- AboutView: add GitHub Sponsors link
- ComposeBox: paste image from clipboard → uploads via nostr.build,
  inserts URL at cursor with "uploading image…" status
