feat(core): RDP client on IronRDP

clients::rdp connects over any caller-dialled TCP stream (direct, proxy or SSH tunnel), upgrades to TLS and logs on with NLA (CredSSP/NTLM), optionally falling back to TLS-only logon for servers without NLA such as xrdp (credentials are passed so they log straight in). The server certificate is pinned through a caller check on its SHA256 fingerprint before any credentials are sent. The desktop decodes into the VNC client's RGBA framebuffer; input (IronRDP's scancode/Unicode/mouse operations), Display Control resizes and the deactivation-reactivation sequence run on the session thread. IronRDP's releases need three vendored patches (vendor/README.md): picky and sspi with their RustCrypto release-candidate pins relaxed so they share russh's stable versions (their own suites, 402 tests, pass against them), and ironrdp-session with two unreleased upstream bitmap fixes (#1486 stride, #1524 RDP6 orientation) without which xrdp desktops render sheared. Verified live against xrdp (scottyhardy/docker-remote-desktop): logon, full desktop rendering, keyboard and mouse input.
