chore(deps): bump livekit protocol, server-sdk-go and pion/webrtc

Dependabot's go-modules bump (#123) fails to build: livekit/protocol
1.51.0 changed TransferSIPParticipant to return
*TransferSIPParticipantResponse, but server-sdk-go v2.18.1 still
returns *emptypb.Empty from its wrapper, so the module no longer
compiles. No tagged server-sdk-go release carries the fix yet, so pin
the SDK to a main pseudo-version (1da58cd, 2026-09-04) which was built
against the new signature and requires go >= 1.26.3.

- github.com/livekit/protocol v1.50.4 -> v1.51.1-0.20260903060125-0cf5ba018b8e
- github.com/livekit/server-sdk-go/v2 v2.18.1 -> v2.18.2-0.20260904062056-1da58cd7b795
- github.com/pion/webrtc/v4 v4.2.18 -> v4.2.19
- go directive 1.26 -> 1.26.3

Supersedes #123.
