release: v1.5.6 (versionCode 10506) — notifications, faster map pins, badges

Rebuilt the release APK so the phone gets everything currently on main:
opt-in on-device notifications (incl. the @capacitor/local-notifications
native plugin), the batched/smoother map markers, profile badges, the
'closest spot to me' Sasquatch intent, and the 'Keep the map free' support
element. Bumps only package.json (version sync script derives versionCode).

+v1.5.6
+
+🛹 The map is quicker off the mark
+- Pins no longer rebuild themselves several times while the map loads, and they
+  stream in instead of freezing the screen in a busy city. Same map, less
+  waiting.
+
+🔔 Notifications (opt-in)
+- Turn them on in Settings -> Notifications and your phone can buzz for DMs,
+  crew invites and join requests, zaps, replies and mentions, and new newsletter
+  drops.
+- Privacy first: nothing new is sent anywhere, and direct-message alerts never
+  unlock your messages — so an Amber user is never asked to approve one just to
+  be told a message arrived.
+- Honest limits: alerts come from the device while the app is running. A fully
+  closed app can't be reached without a push server, which SkateSpots doesn't
+  run — we'd rather say that than pretend otherwise.
+
+🏷️ Badges on your profile
+- A free name@skate-spots.org handle now shows the SkateSpots badge, and you can
+  list your own badges (Cordn, Cashu, NWC, Amber, BTCMap…) as clickable chips.
+
+📍 "Closest spot to me"
+- Ask the Sasquatch where to skate and it can sort by what's nearest — worked
+  out on your device, without sending your location anywhere.
+
+⚡ Keep the map free
+- The Supporters page now has a one-tap way to chip in (zap publicly, or pay
+  quietly), if you want to.
