Switches the GetChannelEvents query from a timestamp-ordered scan to an id-keyset cursor (WHERE id > $cursor ORDER BY id ASC LIMIT $n). The keyset cursor is stable under concurrent inserts and survives a future retention job that prunes the oldest rows: a positional OFFSET would silently skip events whenever rows below the cursor are deleted, while "id > $cursor" keeps advancing past whatever the caller has already seen. The id field is documented in the proto as a server-assigned monotonic identity, so callers persist last_id as their sync watermark. Adds a (channel_id, id) composite index to back the new query; the existing (channel_id, timestamp) index does not cover it and would force a per-channel filter after a global id scan.
