chore(hikes): rsync push/pull for source photos

Add scripts/hike-photos.sh (+ pnpm photos:push / photos:pull) to back up and
restore hike source photos over rsync, keeping them out of git. Transfers
only photo files (images/, private/, root cover.*) — matching the .gitignore
rules — so the versioned text (index.svx, track.gpx, icon.svg) is untouched.
Config via REMOTE / HIKE_PHOTOS_DIR with deploy.sh-style defaults; supports
--dry-run and --delete. No build changes: build-hikes still reads local files
and falls back gracefully when a photo is absent.
