The Reolink RTMP server does not percent-decode query parameter values - it compares the raw bytes from the URL against the stored password. URLSearchParams.set() percent-encodes values when the URL is serialised (WHATWG application/x-www-form-urlencoded), which corrupts passwords containing characters such as '!' (-> '%21'), '#' (-> '%23'), '+' (-> '%2B'), space, etc.
Affected: users whose firmware causes getLoginParameters to return {user, password} (instead of a Login-API token) and whose password contains any of those characters. Symptom: rebroadcast prebuffer fails with 'Socket received FIN' immediately after 'Sending play command'.
Append the RTMP credential pairs as raw bytes instead of going through URLSearchParams. Token-only path is unaffected (hex tokens contain no characters that require encoding). Mirrors the rationale of #1509 for the HTTP API path.
Fixes#2057
