Harden the descriptor conversion in VoipManager::Start

Read the encryption key with one GetMany instead of 256 GetAt calls through a
property fetched each time. It also clamps to what is there rather than throwing
hresult_out_of_bounds out of Start, and drops a copy via a stack array.

pushStun skips an empty host but pushTurn did not, so a server without IPv6
contributed a TURN entry pointing at nothing.

Return the debug info without leaking it

The hand-rolled UTF-8 conversion leaked its buffer on every call and returned it
uninitialized if MultiByteToWideChar failed. The correct one-liner was already
there below it, unreachable — the source of the C4702 warning.

Guard three loose ends in VoipGroupManager

Screencast unmuted the instance directly, leaving m_isMuted stale so IsMuted
reported the opposite of the truth; route it through the setter. A screencast
with no audio to send stays muted, which is what it means.

The quality switch had no default, so an unrecognised value read an
uninitialised local. AddIncomingVideoOutput took get_self on the sink without
checking it, unlike its VoipManager counterpart.
