Implement state, action, and view layers for both list screens: - Issue List: keyset pagination, snapshot fence, filter DSL, label aggregation - MR List: mirrors Issue pattern with draft/reviewer/target branch filters - Migration 027: covering indexes for TUI list screen queries - Updated Msg types to use typed Page structs instead of raw Vec<Row> - 303 tests passing, clippy clean Beads: bd-3ei1, bd-2kr0, bd-3pm2
