Both Telegram and Discord deadline services were querying ALL due
proposals without filtering by source_platform. If the Telegram
service reached a Discord proposal first, it finalized the DB state
but skipped message handling. The Discord service then saw status
!= 'Voting' and never updated the Discord vote message.
Fix: GetDueProposalIdsAsync now accepts a sourcePlatform parameter
and filters at the DB level. Each service only processes its own
platform's proposals.

Move neutral join/leave handlers into GmRelay.Shared so Telegram and Discord share capacity, waitlist, duplicate-click, and schedule-update behavior.
Add Discord component routing for join_session and leave_session buttons with deferred ephemeral replies and serialized schedule message updates.
Bump version to 2.5.0 and update Discord docs.
