settings: the assistant's daemon config, tools, and Ask presets

Two settings pages for desktop-assistant.

Assistant edits the daemon's config.toml: server, temperature, tool
rounds, thinking, the system prompt, and the [env] values its tools
read; a switch per tool renames tools/<name>.toml to .toml.off, which
the daemon's glob skips. The daemon reads all of it at startup only, so
the page says when a change is pending and Restart runs assistant.sh
restart, showing its status when the daemon does not come back.

The file is edited line by line, like autostart.lua, so the comments
the example ships with survive: unset keys stay commented out in place.
Every write parses the whole new file with tomllib first and replaces
the old one atomically, so no edit can leave a config the daemon will
not start with. Defaults are read from assistant.py --defaults rather
than copied into QML.

Ask presets edits the canvas's canned questions, which Prefs already
stored for exactly this page: label, question, and the kinds each is
offered for. They apply live.
