UNITRONIX 1508c739b2 fix(api): Go :21114 default API and Node :21121 compat proxy (#160 )

RustDesk clients could not log in after v3 when handlers moved to Go but
nothing listened on :21121 (API_ENABLED off) or Go bound the wrong port.
Go serves /api/login on 21114; the console proxies legacy :21121 URLs to
Go. Installers repair .env/systemd, Docker publishes both ports, and
firewall rules allow 21114 and 21121 on full installs.

Also includes betterdesk-support-agent (Fyne desktop helper) and
docs/important/ operator notes (API ports, update flow, agent roadmap).

rdclient protobuf enum encoding pitfall

web-nodejs/public/js/rdclient/protocol.js serializeMessage MUST use Message.fromObject(obj) (NOT Message.create(obj)) before .encode().
protobuf.js create() does NOT convert string enum names -> numeric values. So keyEvent.controlKey: 'Backspace' / mode: 'Legacy' encoded as 0 (Unknown) -> all non-character keys silently dropped by peer; only numeric chr letters worked.
fromObject() converts enum name strings to numbers AND preserves Uint8Array byte fields (clipboard content, file blocks, password, pk). Verified round-trip.
Fixed in commit 1411719 (main).
input.js KEY_MAP sends ControlKey NAME strings (Backspace/Return/Space/...). ControlKey enum values: Backspace=2, Return=27, Space=30, Tab=31, Alt=1, Control=4, Shift=29, Meta=23, Escape=8 (see protos/message.proto).
Validate JS edits: cd web-nodejs && node --check public/js/rdclient/<file>.js.
protobufjs not an npm dep; vendored at public/js/vendor/protobuf.min.js.
