feat(ui): show MeshCore version large and plus version in splash bar

Add MESHCORE_VERSION build flag ("1.15") to companion base configs.
Splash screen now shows MESHCORE_VERSION in the large text and the
plus firmware version (stripped of commit hash) in the Plus bar,
e.g. "1.15" large + "Plus v1.11 for Wio" below.

Change CI tag pattern to v* and simplify version extraction so tag
v1.11 maps directly to FIRMWARE_VERSION=v1.11.
