feat(assistant): trip assistant chat with your own AI connection

Adds an in-app assistant that reads and plans the open trip. Users connect their own provider (Sign in with ChatGPT, or an Anthropic, OpenAI, Gemini or OpenRouter key) or use the one the admin set up, including a custom OpenAI-compatible server. It is an addon and only shows while a connection is usable. The chat runs on the existing MCP tools, pinned to the trip. Every change is held as a change card the user applies or discards, and applied changes can be undone. On the desktop it is a floating window that can be moved and resized; on the phone it is fullscreen. Search results show as place cards that can go onto a day, weather lookups as a strip, proposed places as ghost markers on the map with a before/after switch, and an answer can be shared into the trip chat. Booking files can be dropped in and are read into change cards.

+ * FE-AI-MAPMODEL-001 to FE-AI-MAPMODEL-009
+ *
+ * What the map makes of the assistant's chat, without React or a store: which
+ * changes stand on the map as ghosts and until when, the box a running step
+ * searches, the days a block touches, the "before" plan laid over the view,
+ * and how far the floating window reaches over the map.
