chore: bump version to 3.0.21 [skip ci]

* fix(journey): remove photo upload count limit and surface upload errors (#997)

Removes the arbitrary 10-file cap on journey entry photo uploads and 20-file
cap on gallery uploads. MulterErrors now return proper 4xx responses instead
of 500, and the client surfaces the server error message via toast rather than
silently trapping the user in the post editor overlay.

* fix(planner): remove correct assignment when place assigned to same day multiple times

When a place was assigned to the same day more than once, the "Remove from day"
button in PlaceInspector always deleted the first assignment (Array.find on
place.id) instead of the currently selected one. Now prefers selectedAssignmentId
when available.

Fixes #1005

* fix(map): enable 3D terrain for Mapbox outdoors style in trip planner

wantsTerrain() only matched satellite styles, so the outdoors-v12 style
was flat in the planner despite showing correct 3D terrain in the settings
preview. Added outdoors-v12 to the allowlist; marker drift is already
handled by syncMarkerAltitudes().

Fixes #1002

* fix(maps): send Referer header on Google API calls when APP_URL is set

Supports HTTP referrer restrictions on GCP API keys. Documents the
restriction types and photo troubleshooting steps in the wiki.

+### `HOST` — Source and Proxmox installs only
+
+By default TREK binds to all network interfaces (`0.0.0.0`), which is the correct behaviour inside a container because Docker handles port exposure at the host level. Setting `HOST` overrides the bind address at the Node.js level.
+
+**When to use it:** only when running TREK directly on a host (git sources or the [Proxmox community script](Install-Proxmox)) and you need to restrict which interface the server listens on — for example, to expose TREK only on a LAN interface while keeping it off the public-facing one.
+
+**Never set `HOST` in Docker, Docker Compose, Helm, or Unraid deployments.** Use Docker's `-p <host-ip>:<host-port>:<container-port>` syntax or your orchestrator's port binding instead.
+
+```
+# .env — source / Proxmox installs only
+HOST=10.0.0.72   # bind only on this LAN interface
+PORT=3001
+```
