feat: RDP profiles, sessions and viewer

- Protocol::Rdp with RdpConfig (domain, password mode, certificate
  policy, TLS-only fallback, fixed or tab-sized resolution, SOCKS5/HTTP
  proxy, SSH tunnel); migration 008 adds rdp_config and drops the
  protocol CHECK constraint so new protocols no longer need a rebuild.
- Session manager: connect_rdp dials directly, via the shared proxy
  module (proxy password from the secret store) or an SSH tunnel; the
  server certificate goes through the known-hosts check (key type
  rdp-tls); a tab-sized desktop uses the tab's reported pixel size, and
  resizes wait until the server opens Display Control. Rejected NLA
  passwords count as auth failures, so a saved one is asked again.
- The VNC viewer becomes DesktopView for both protocols; a small adapter
  turns its keysyms and pointer masks into RDP scancodes, Unicode keys,
  buttons and wheel events. For RDP, Paste Clipboard types the text.
- Profile editor RDP section, Quick Connect, badges, docs.

Verified against xrdp in the app: logon, desktop, input, and connections
through SOCKS5 and HTTP CONNECT relays. Not verified here: Windows/NLA
servers, the SSH tunnel route, and Display Control resizing (xrdp
0.9.24 never opened the channel).

# Nexus Terminal
**A native desktop client for SSH, Telnet, RAW TCP, Serial, VNC, IRC, GitHub and local terminals — with secure credential handling and a focused, multi-session workflow.**
**A native desktop client for SSH, Telnet, RAW TCP, Serial, VNC, RDP, IRC, GitHub and local terminals — with secure credential handling and a focused, multi-session workflow.**
Nexus Terminal helps you manage many connections at once, keep terminal work organised, and move files with confidence. It is a single Rust application with no webview, so it starts quickly and stays responsive under heavy terminal output.
## Highlights
- SSH, Telnet, RAW TCP, Serial, VNC, IRC, GitHub and local terminal sessions in one app
- SSH, Telnet, RAW TCP, Serial, VNC, RDP, IRC, GitHub and local terminal sessions in one app
- Tabbed sessions with split panes, pinning and drag-to-reorder
- SFTP browser with drag-and-drop uploads and a permission-aware directory picker
- SSH jump hosts, SOCKS5/HTTP proxies, local and remote port forwards, agent forwarding and TOTP auto-fill
- Serial consoles with full line settings (baud, data bits, parity, stop bits, flow control)
- Native VNC viewer, optionally tunnelled over SSH
- Native VNC and RDP viewers; RDP with NLA, certificate pinning, and SOCKS5/HTTP proxy or SSH tunnel routes
- Disconnected overlay with one-click reconnect, and auto-reconnect with backoff
- Broadcast input, snippets, trigger rules and terminal search
- Session recording (asciicast v2) and playback
