- Nav: MIDDLE_SLOTS 3->4 and add 'mints' to the default middle + desktop tabs,
so the Cashu mints directory is reachable on the phone out of the box (also
still linked from Wallet; any of the 4 slots can be swapped via long-press).
- Directions: RouteDialog now seeds the origin from the last known location and
draws immediately, then refines with a live fix — no more hanging on 'Finding
your location…'. Shortened the web geolocation fallback 15s -> 8s.
- Amber: /api/ai/status is now public (it only reports a small balance), so
showing the AI balance no longer signs NIP-98 / opens the signer. The signer is
reserved for actions that actually need it.
