* fix(playback): escape commas in mpv header fields on the TS paths

PR #1321 fixed the comma truncation of --http-header-fields inside the
native embedded-mpv addon, but the same OPT_STRINGLIST parsing bites
three TypeScript call sites that join header fields with ',':

- external MPV CLI launch (--http-header-fields=...)
- external MPV instance reuse (set_property http-header-fields)
- embedded MPV frame-copy loadfile options (opt.http-header-fields);
  the helper's %len% quoting protects only the option-list level, mpv
  still stringlist-parses the value afterwards

The Stalker MAG user agent contains "(KHTML, like Gecko)", so strict
portals received a truncated X-User-Agent and rejected live streams
with HTTP 400 (#910). Escape backslashes and commas per field with the
same scheme as the native fix, via a shared util.

* test(playback): cover the reused-instance IPC header escaping

Review follow-up (Greptile on #1323): the regression coverage only
exercised the CLI spawn path. Capture the JSON IPC traffic of a second,
reused mpv launch and assert the escaped MAG user agent survives the
set_property http-header-fields transport, so later serialization
changes cannot silently reintroduce truncated headers. net is mocked
with a passthrough default because the VLC specs bind a real ephemeral
port via createServer.

External MPV and the embedded MPV frame-copy engine no longer truncate HTTP headers that contain commas — most notably the Stalker MAG user agent. Strict portals validated that header and rejected live streams with HTTP 400, so channels that only worked in VLC now also play through MPV. Completes the same fix that landed for the native embedded MPV view.
