fix(acp,tui): rename /compact to /compress and /density to resolve command collision

- acp_adapter/server.py: rename compact -> compress for context compression command
- tui_gateway/server.py: rename /compact -> /density for display density toggle
- ui-tui/core.ts: rename compact -> density for display density toggle
- Internal config keys (tui_compact) and UI state (ctx.ui.compact) unchanged
