docs: add missing third-party notices

[EtienneLescot]

Three components the installers ship had no entry in THIRD-PARTY-NOTICES.md:

• the web-demuxer WebAssembly module, MIT licensed, with LGPL FFmpeg code inside;
• the crates compiled into the compositor addon, grouped by license;
• helper code taken from Recordly while it was MIT licensed.

Notices only, no code change.

include the applicable license texts and copyright notices for crates compiled
into compositor_view.node; include full MIT notices and Apache-2.0 license
copies, not only links to source packages.
- Line 172: Update the license attribution in THIRD-PARTY-NOTICES to distinguish
Recordly-specific material from the original OpenScreen assets. Identify
Cursor=Default.svg and Cursor=Beachball.svg as original OpenScreen files covered
by the existing notice in LICENSE.
