v1.1.0: explorer tab, bootstrap fixes, full theme overlay merge

Explorer tab:
- New block explorer tab with search, chain stats, mempool info,
  recent blocks table, block detail modal with tx expansion
- Sidebar nav entry, i18n strings, ui.toml layout values

Bootstrap fixes:
- Move wizard Done handler into render() — was dead code, preventing
  startEmbeddedDaemon() and tryConnect() from firing post-wizard
- Stop deleting BDB database/ dir during cleanup — caused LSN mismatch
  that salvaged wallet.dat into wallet.{timestamp}.bak
- Add banlist.dat, db.log, .lock to cleanup file list
- Fatal extraction failure for blocks/ and chainstate/ files
- Verification progress: split SHA-256 (0-50%) and MD5 (50-100%)

Theme system:
- Expand overlay merge to apply ALL sections (tabs, dialogs, components,
  screens, flat sections), not just theme+backdrop+effects
- Add screens and security section parsing to UISchema
- Build-time theme expansion via expand_themes.py (CMake + build.sh)

Other:
- Version bump to 1.1.0
- WalletState::clear() resets all fields (sync, daemon info, etc.)
- Sidebar item-height 42 → 36
