fix: extract clean_lines/parse_room_output/normalize_event to module level (#1509)

Test file imports clean_lines, parse_room_output, normalize_event from
nexus.evennia_ws_bridge, but they were nested inside playback() function.
Moved all three to module level so they're importable.

Also moved actor_located/command_issued/command_result/room_snapshot/session_bound
imports from nested playback() to module-level import block.

playback() now calls module-level functions directly.
