Use the AI sparkle for the assistant action

Material's auto_awesome, the shape that has come to mean "ask a model" — the
same one Gemini and the rest use. Theirs are trademarks and have no place in an
F-Droid build; this one ships under the Apache licence already covering the
app's icons.

It now marks the action everywhere it appears: the selection-menu entry, the
lookup screen's top bar, and the translate and explain buttons in the reader,
which were text alone.
