1.5.1: refined office, chat in the app language, current OpenAI models, own connector keys

- Home: the goal title box is two line boxes tall (2.8em), so a third line no longer peeks out.
- Chat messages, reply fallbacks and assignment DMs follow the app display language; tasks and documents keep the working language.
- OpenAI and GPT-account model lists match OpenAI's current line-up; default gpt-6.1-sol.
- Onboarding connectors step takes the operator's Composio and logo.dev keys, then lists the toolkits the Composio project enables; without a key Connectors leaves the sidebar.
- Google Antigravity removed end to end (migration 111), with the remote-revocation path only it used.
- Office: 2x pixel people with outlines, rim light, walk, typing and blink; dithered real-clock lighting; detailed furniture and floors.
- Per-agent model picker lists the provider's whole model list, live when connected.
- Chat wake context breaks same-millisecond ties by insertion order; the mid-run inbox dedupes by message id.
- The stored "clock" theme reads back instead of falling to "system".
